Given the number of division there are, and the number of seasons now that divisions have been generated (4), the odds are very high that we'd get at least one collision. I'd bet that there's been some before and it's just gone unnoticed.

Are you sure?

Looks like you only need 23 people to hit 50%.

Ya, whenever I hear the example, it's always 25, but probably because that's just an even number.

I remember having this discussion with my brother years and years ago, he didn't believe it either, so we started looking at baseball teams (every team 25 players on its roster), we went through about 16 teams and 10 or 11 teams already had two players with the same birthday, so we stopped.

RE: Still neck division
Pretty sure it's about probabilities:
Need to find the percentage of no people have birthdays together (this is continuing to assume that no two people have the same birthday)
For 1 person, there is 365/365
For 2 people, I would say 364/365 to keep it simple, although the fraction is much weirder than that due to leap years.
3 people: 364/365 * 363/365
4 people: 364/365 * 363/365 * 362/365
5 people: 364/365 * ... * 361/365
And so on.
Even for 10 people: already ~12% chance that 2 people will have the same birthday. (because ~88% chance that they will not have the same birthday)
