Anyone have the correct answer to this problem?

How many people do you need in a room before it's likely that two people have the same birthday?

We had this a probability class one year. I'm fairly certain it was 18, but the more I think about it, the more I think it may be lower than that. If you know the math to get it, then I'd love to see it too.

I've heard of this too. It's called the birthday paradox. I remember it's a fairly simple calculation. I'll see if I can come up with it. :)
