I believe you mean to say, equally probable. By stating they are separate events, I assume that they are independent and that there is a single unique outcome to each ev…ent that can be identified. Ok, then the chance of each event or outcome is 1/10. (MORE)

Probability tells you the chance that something will happen. For example: There are 3 red tiles, 5 green tiles and 2 pink tiles in a bag. What is the probability of picking a …red tile? First you find out how many red tiles there are. There are 3 red tiles. Then, you add up all the tiles. Altogether there are 10 tiles. So, there is a 3/10 probability that you will pick a red tile.

Advantages and disadvantages of probability sampling: Advantages: Since it is done at random, the whole process is unbiased. This is good to use in smaller populations, of c…ourse it doesn't 100% protect from bias (depending on the question). But this option is a quicker way of achieving information. Disadvantages: As i said before, depending on your question it cannot prevent from bias. Also, if you are sampling information from a large population this will take too much time and patience. There is also no guarantee that what these people say, represents what another group of people believe. Non-probability sampling: Advantages: This is more accurate because you are targeting a specific group, therefore your answers will be similar to what the rest of the population (of this group) will answer. Disadvantages: This is more biased, because the individuals chosen are not at random. They also might not represent what another population thinks (MORE)

11 * * * * * No, on two counts. The sample space is the possible outcomes of the experiment, not the NUMBER of possible outcomes. And, as far as this experiment is concerned,… there is no way to distinguish between the two occurrences of b and i. So there are, in fact, only 9 possible outcomes. Two of these outcomes have a higher probability but that is a different matter. The sample space is {p, r , o , b, a, i, l, t, y} a set of cardinality 9. (MORE)

The short answer is "random sample," but that, unfortunately, is neither specific nor complete. It is not specific because there are forms of random sampling where selection p…robabilities are not constant. It is not complete because there are many different ways to conduct random sampling with equal selection probabilities. "Simple random sampling" occurs when you can perform a process that, for all practical purposes, behaves like writing down the identifier of each population member on a piece of paper, putting all the pieces into a box, mixing them thoroughly, and pulling out a few of them one by one (without replacing them in the box). Nowadays we use a computer to do this job, because it's faster and more reliable (it is notoriously difficult to mix pieces of paper perfectly randomly). The computer needs a complete list of all the population members: this is called a sampling frame. Here is an example of random sampling that is not simple but still selects every population member with equal probability. Suppose you want to sample half the students in a classroom of 30. Ask them to line up. Flip a fair coin: if it's heads, pick the first, third, ..., 29th in line. If tails, pick the second, fourth, ..., 30th. Any individual student has a 50% chance of being part of the sample, so each student has an equal probability of being included. However, if you lined up the students boy-girl-boy-girl, etc., the samples themselves wouldn't look very random: they will either be mostly boys or mostly girls. It's still random though, because it's determined by the flip of a coin. The example highlights a subtle but important property of a random sample: in many cases, you want the selection of population members to be independent. This means the probability of selecting one member is not affected by which other members are selected. In simple random sampling, independence holds; in the second example (a form of gridded sampling), there is complete dependence: no student can be chosen along with either of their neighbors in line, for instance. Simple random sampling is ideal for many purposes but often cannot be carried out in practice because it is not feasible (you might not be able to construct a sampling frame) or costs too much. Often, more complicated procedures, such as hierarchical sampling, are carried out to overcome these limitations. (An example of hierarchical sampling is when an epidemiologist selects a city at random, then selects households at random within the city, then selects children at random within each household to study. Doing it this way can require much less travel than selecting children at random from all over the state.) These procedures might or might not select population members with equal probability. Usually the selection is not independent, either. When the probabilities are unequal, they can be figured out and used as weights in statistical analysis of the data. Results can also be adjusted for lack of independence. A good, readable, non-technical introduction to sampling and simple random samples is the textbook Statistics by Freedman, Pisani, and Purves. Any edition is fine. Steven Thompson's book Sampling discusses dozens of different sampling procedures and explains the theory behind each one. (MORE)

A probability sampling method is any method of sampling that utilizes some form of random selection. See: http://www.socialresearchmethods.net/kb/sampprob.php … The simple random sample is an assumption when the chi-square distribution is used as the sampling distribution of the calculated variance (s^2). The second assumption is that the particular variable is normally distributed. It may not be in the sample, but it is assumed that the variable is normally distributed in the population. For a very good discussion of the chi-square test, see: http://en.wikipedia.org/wiki/Pearson%27s_chi-square_test (MORE)

They're the world's real life warriors!
At 19 months old, Trucker was diagnosed with stage IV neuroblastoma. Treatment often takes him to New York, which is a long a…way from his home in Hawaii. But thanks to the friendly faces at the New York Fire Department, NYC is finally starting to feel much more like a home away from home.
But how does a 3-year-old befriend a fire department?
It all started when FDNY Captain Jim Grismer made an appearance at the Ronald McDonald House. He'd arrived in response to a call, and once inside, he was greeted by the infectious, admiration-filled smile of the little firefighter enthusiast.
When the folks at the fire commissioner's office set eyes on this precious photo of Trucker and Grismer, they knew they needed this bright-eyed boy as a member of their team. By the end of May 2016, Trucker will be just that—an honorary firefighter!
According to CureSearch.org, 43 children are diagnosed with cancer each day. Fortunately, as scientists and medical professionals work tirelessly to treat the disease (and one day to prevent it entirely), there's another team out there involved in the fight against life-threatening illnesses—an army of wish-granting angels who bring joy to these kids' during their grueling recovery journeys.
Check out these 10 other dream-come-true stories that are just as touching as Trucker's.
Wish: Darius, a 9-year-old who goes by "Dawa," has a brain tumor. He longed to have a dog by his side through thick and thin.
"He wanted a best friend; he wanted someone who would lay with him when he wasn't feeling well. He wanted someone that would play with him," Make-A-Wish Arizona volunteer Crystal Sixberry told Fox 10. "He wanted a dog that could do tricks."
Fortunately, a Humane Society rescue—coincidentally named Lucky—was looking for a pal as well! Just as predicted, these two are the perfect pair. According to the caption beneath their introduction video (which you can watch [here](https://www.youtube.com/watch?v=7yDsRbc9jwU)), "within no time at all, Darius had Lucky performing all of his tricks and leading Darius, with a huge smile on his face, around in his wheelchair."
Wish: Ryan Wilcox, 18, suffers from secondary myelodysplastic syndrome and has always dreamt of meeting "The Avengers" cast members.
Ryan was diagnosed with a brain tumor at 3 years old and has been fighting illness ever since. When Gwyneth Paltrow (who plays Iron Man's flame Pepper Potts) heard Ryan's story, she took to Instagram and posted a call to action. "(Ryan) isn't doing too well and this would be a major way to boost his spirits..." Paltrow explained. "Please share this to help get the attention of Chris [Evans], Robert [Downey Jr.], Scarlett [Johansson], and the rest of 'The Avengers' cast and try to make his dream come true!"
Initially, Evans (Captain America) responded via video message, but two weeks later he, Paltrow, and Downey (Iron Man) dropped by to say hello in person!
Wish: Emma Payton, 10; Harley Renshaw, 6; Luke Chapman, 9; Niamh Brown, 10; and Ollie Carroll, 5, were granted the opportunity to be the stars of a U.K.–based superhero extravaganza.
Thanks to the charities When You Wish Upon A Star and Key 103's Cash for Kids, Manchester, England, residents had the pleasure of witnessing the spectacle of Supergirl (Emma), Captain America (Harley), Iron Man (Luke Chapman), "The Incredibles'" Violet (Niamh), and Spiderman (Ollie) gathered together in Albert Square. Before a crowd of hundreds, these brave children—all of whom are battling life-threatening illnesses—reminded their supporters that the good guys will always prevail!
The city accomplished something incredible in their honor—residents raised thousands to keep wishes coming for other children who are in their shoes: £100k (approx. $145K USD) to be exact!
Wish: Jackie, 13—who was born with hypoplastic heart syndrome—wanted her very own, in-home nursery where she could play with and care for her baby dolls.
After powering through four open-heart surgeries, the team at Make-A-Wish Kansas made it their mission to do something extra special for Jackie. Surviving those intensive surgeries isn't even Jackie's greatest feat—she's exceeded her life expectancy by six years!
With the financial assistance of the non-profit Jewelers for Children, Make-A-Wish brought Jackie's vision for a nursery to life, painting the space pink and adorning it with her favorite birds (owls) before filling it with baby doll must-haves, including a rocking chair, changing tables, and a motorized swing. She also received two new babies to love, one of which she has named Benjamin.
Wish: Kayla, 13, had the same wish as many girls her age—to go on a shopping spree!
This brain tumor battling teen and her family got to shop until they dropped at O'ahu's Ala Moana Center, but unbeknownst to her, Make-A-Wish and the Jewelers for Children Association had another surprise in store for her! Not long after she returned from her shopping excursion, she was taken to Precision Goldsmiths in Wailuku. There she was offered a present that, according to a Make-a-Wish representative, "would hold meaning for her for years to come; a gift that would remind her of her journey to healing."
The surprise: a gold bracelet custom-crafted just for her!
Wish: Eric, 13, wasn't about to let his life-threatening illness prevent him from meeting his favorite athlete, Kyle Korver.
When Eric was asked to make a wish, he offered a two-part answer. Firstly, it was his dream to watch an Atlanta Hawks basketball home game, and secondly, he hoped that a meeting with his absolute favorite player, Kyle Korver, could be arranged. His wish was Make-A-Wish Mississipi's command, with the help of sponsor Watertree Health. Not only did Eric get to cheer on the team courtside and meet his personal MVP, he actually got to play in the pre-game warm-up! Before heading home, he was taken on private tours of the World of Coca-Cola Museum and the College Football Hall of Fame.
Wish: Karlee Drew, 9, suffers from acute myeloid leukemia and has long fantasized about meeting Justin Bieber.
Actually, her dream also involved swimming with the singer/songwriter AND dolphins, but her peripherally inserted central catheter (PICC) line would have made that a bit tricky. Fortunately, a meet-and-greet with the star was easy to pull off!
“Justin is a long-standing, committed and generous wish granter,” a Make-A-Wish spokesperson said. “Justin’s dedication is evidenced by the fact that he has granted a wish in almost every city during his current tour.”
Karlee couldn't have looked cuter for her big moment with Bieber, sporting a dazzling gold wide-brimmed hat and dress. Her mom, Pam, described the magical moment as the "happiest I have seen Karlee in a long time!"
Wish: As Rylee Durham bravely battles Noonan syndrome, she gets enjoyment from rooting for her favorite NASCAR driver—her hope being to meet him one day.
Determination drives Rylee's every move, so when her NASCAR hero, Kasey Kahne, called to ask her to join him for a race in Daytona, she jumped at the chance. Although the experience of waving to fans while taking a lap around the track and meeting Kahne were gifts for Rylee, she actually brought her own gift for the driver—two pennies, which she deemed lucky because one featured her birth year and the other his. The coins were tucked away in Kahne's car as just one component of the beautiful bond the two now share (along with their secret handshake)! Check out [footage](https://www.youtube.com/watch?v=fxEjsFv3j5Q) from the memorable meeting!
Wish: Battling congenital biliary atresia, Wyatt, who is 12 years old, loves tuning into Animal Planet and wished to meet one of his favorite show hosts, Jeremy Wade.
It's not every day that someone gets to hold a lamprey (a jawless fish)! But to Wyatt's excitement, that's exactly how his Make-A-Wish–arranged Animal Planet experience started—with "River Monsters" host, Jeremy Wade, by his side, of course. During the course of the day, Wyatt got to learn about the magic of video editing, star in a green screen promo, scoop up lots of free swag, munch on a lunch buffet, and, quite unexpectedly, meet another one of his favorite people, Pete Nelson of "Treehouse Masters."
According to Wyatt, the day was one of the best of his life (next to receiving a new liver)!
Wish: Sophia, 8, loves listening to the weather, so when she was granted a wish after doctors detected a tumor behind her eye, she knew exactly where she wanted to visit—a weather channel!
Mesmerized by Mother Nature, Sophia is in awe of the ever-changing atmosphere. When she was invited to tour Atlanta's Weather Channel studio, there were so many aspects of the experience she'd never anticipated—her name being plastered on the walls and T-shirts of the employees, for example. But the studio's hospitality was hardly the most memorable surprise. Chatting with meteorologists and sitting in the director's chair was cool and all, but absolutely nothing could top her time on camera! That's right—much to her surprise and delight, Sophia got to spill what the weather had up its sleeves on live television. Watch her darling debut [video](https://www.youtube.com/watch?v=IofV6XZiH2k).
As is evident from these 10 uplifting stories, just like the kids themselves, no two wishes are the same! But they do have one thing in common and that's their ability to lift spirits when at their lowest.
