you wont get your birthday every year
Just over 7 out of 12.
the probability is 3/12 or 1/4
For ease of answering, we will work under the assumption that the probability of someone being born within any given month is equal to that of any other month. Allowing that assumption, we can look at that question a slightly different way and say "What is the probability that all people in a group of six would each be born in a different month?" The answer to that would be 12/12 * 11/12 * 10/12 * 9/12 * 8/12 * 7/12, which can also be expressed as (12! / 6!) / 126, and comes out to 665280 / 2985984, which equals 385 / 1728. The probability of at least two being being born in the same month would then be: 1 - 385 / 1728 = 1343 / 1728 ≈ 0.7772, or approximately 77.72%
1972, depending on your birth month
if we assume that the probability for a girl being born is the same as a boy being born: (1/2)^6 = 0.015625 = 1.5625%
1 out of 7 I think so!
The probability of two people's birthday being the same is actually more likely than many would think. The key thing is to note that it doesn't matter what the first person's birthday is. All we need to work out is the probability that the second person has a birthday on any specific day. This probability is 1/365.25 The probability that they were born on June 10th is 1/365.25. The probability that they were born on February 2nd is 1/365.25 and the probability that they were born on the same day as you is 1/365.25
364 out of 365
Probability : 1/1461 or 0.068 %
Rather a vague question. Are the people related? Obviously thousands of people are born in every month, so I guess you mean people who are connected in some way.

No, it is false. There is a nearly equal probability of being born at any time day or night.
