The key feature is that each sample of the given size has the same probability of being selected as the sample. Equivalently, each unit in the population has the same probab…ility of being included in the sample. (MORE)

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)

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)

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)

In the context of a sample of size n out of a population of N , any sample of size n has the same probability of being selected. This is equivalent to the statement that …any member of the population has the same probability of being included in the sample. (MORE)

sample n equals 37 sorry and if you could write the equation that would be helpful
