So we can work it out like this: First we assume that a first person with a birthday exists. The probability of this person 1 having a birthday is \( \frac{365}{365} \). Then we multiply that number by the probability that person 2 doesn't share the same birthday: \( \frac{364}{365

WebThe birthday problem asks for the probability that at least two people in a group of n individuals share the same birthday. This probability is surprisingly high even for relatively small n, due to the fact that there are only 365 possible birthdays, which means that the probability of any two people sharing a birthday is approximately 1/365. ...
