The Birthday Problem

I just found out I was born on the very same day as a friend of mine in the office. I looked up something I was never very sure about, which is the likelihood of that happening in groups. I had heard it was more or less 100% when you get 50 people, and that never made sense to me.

Indeed, I was wrong. In our 62-person office, it's only a little bit higher than 99%.
