Birthday paradox - Try this outWatch
Don't know if you've heard of the birthday paradox, but it basically states that once you reach 57 people in a room there is a 99% chance that they share the same birthday.
So to try this out, just post your birthday and we'll see how many people it takes before a birthday is shared
To start off - June 18th
I have no idea how that works since the odds are 1 in 365 but ill go with it.
2 people, only 1 way in which the birthday can be shared
3 people there are 3 ways
4 people there are 6 ways
5 people there are 10 ways
and at 57 people, there are 1596 possible combinations!
Hence the high chance at such a low number!
