(365 kn)!365n 1!: This completes the solution to the Almost Birthday Problem. However, similar to the Basic Birthday Problem, this can be phrased in the more classical way: WebBy the 26th child the probability of no match is down to 0.4018, which leaves close to a 60% chance of matching birthdays. In a classroom with 30 students, your odds of a match are better than 70%. Suppose the group size is 25. The number of birthday possibilities is 365 25. The number of these scenarios with NO birthdays the same is 365*364 ...

WebHere is slightly simplified R code for finding the probability of at least one birthday match and the expected number of matches in a room with 23 randomly chosen people. The number of matches is the total number of 'redundant' birthdays. So if A and B share a birthday and C and D share a birthday, that is two matches.
