What is the smallest number of people in a room where the probability of two of them having the same birthday is at least 50 percent?

23. The probability that at least two people in a room share a birthday can be expressed more simply, mathematically, as 1 minus the probability that nobody in the room shares a birthday.Imagine a fairly simple example of a room with only three people. The probability that any two share a birthday is :1 - [ 365/365 x 364/365 x 363/365]i.e. 1-P(none of them share a birthday)=1 - [ (365x364x363) / 3653 ]=0.8%Similarly,P(any two share a birthday in a room of 4 people)= 1 - [ 365x364x363x362 / 3654 ] = 1.6%If you keep following that logic eventually you getP(any two share a birthday in a room of 23 people)=1 - [(365x364x...x344x343) / 36523 ] = 51%

What are the chances of 3 people in an office of 6 having the same birthday?

The probability that there will be 3 people born on one birthday, and 3 people born on a different birthday is 1x(1/365)2 x (364/365)3 as it doesn't matter which birthday is the one being shared. This number then needs to be multiplied by the number of possible ways the people can be arranged. For example it could be persons a, b and c sharing a birthday, or it could be persons c, e and f. The number of ways they can be arranged is 20, so multiply by 20 and we get 0.00014889. Thus there is a 0.014889% chance that an office of 6 people will have 3 who share a birthday.
