Birthday Paradox

Happy Birthday to More-than-one-person...

A couple of years ago I saw something called the birthday paradox. It was something about the probability that any two people in a certain room with x people will have the same birthday.

What makes the problem a paradox is that the actual chance is a lot higher than you'd think. In fact, in a room with 23 people, it's 50-50. That's cray-cray when you think about it: of 365 days, two on the same day?

The graph below tells us the chance (y) for the number of people (x).

Nothing much to say hoy...

Stay coolio,
John
