assuming that the probability of being born in may is equal to all other months then one person born in may is 1/12, so 2 people born in may is 1/12*1/12=1/144
2:7 edit: That makes the assumption that: -birth isn't induced for various reasons - people tend to try for induced births more on weekends so that it doesn't interfere with the work week -the ratio of people born on any given day of the week is 1:1:1:1:1:1:1
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.
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!
50% then 25%
Birthdays are not uniformly distributed over the year. Also, if you were born on 29 February, for example, the probability would be much smaller. Ignoring these two factors, the probability is 0.0082
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

Random - musician - was born on 1977-09-03.

the probability is 3/12 or 1/4
Robert Random was born on January 29, 1943, in Chilliwack, British Columbia, Canada.
The dinosaurs were born because nature selected them.
There are 30 days in april. 10 of these days are after the 20th, so the probability will be 10 out of 30, or when we simplify 1 out of 3
