How large does a random group of people have to be for there to be a 50% chance that at least two of the people will share a birthday?.

Given n people, and given n days in a year, the reasoning in part (a) shows that the probability that no two people have the same birthday is μ ¶ μ ¶ μ ¶.

Webthe birthday problem (also called the birthday paradox) deals with the probability that in a set of n n randomly selected people, at least two people share the same birthday.

Webthis is easily determined as follows:

We figure out m, n later.

We will put m balls into n boxes uniformly at random.

Webthe birthday paradox, also known as the birthday problem, states that in a random group of 23 people, there is about a 50 percent chance that two people have the same birthday.

The probability the first two people have different birthdays is (1 1=365).
