That....Makes no sense to me, please explain.
My guess is this is a completely random/bogus statistic, but we can examine it if you wish.
There are 365 days in a year.
There are 12 months in a year.
If we took a truly random sample of 23 people, according to this random chart I pulled up, we would see two people in every month, except August, which would have 3.
Each month has on average 30.4375 days (including February 29th every four years) which would mean that there would be a 6.6% chance for every month that the same day and month would be shared by two people, except for in August, which would have a 9.9% chance of a shared date.
Basically, a low chance from a truly random sample, but not impossible.
I'm thinking that the myth/rumor/whatever it is he's saying comes from is if you add up the chance for each month, which ends with an 82.5% chance of a shared date. Unfortunately, that's not how odds work. The fact remains that your % chance of someone sharing a birthday with someone else in the room, assuming it is truly random, is 23/365, which is 6.3%. (The reason for the percent deviation is because I'm not paying attention and accidentally made it 25 people by assigning it to two every month except for 3 in August and I don't feel like going back and fixing it.)
So yeah. Soccerdude's little "fact" is bunk.
