bacony?

Chocolate chip cookies made with bacon grease in place of butter taste disappointingly unlike bacon. Odd that there was a hint of bacon in the batter, but not the finished product.

birthday odds

So let's say you have a group of ten people, and you want to determine the odds of two of them having the same birthday. I'm not certain, but I think it goes like this...

One person has 357 of 365 chances not to match. So that's 355/365. Each person has this chance for each of the other nine people. So anyone's odds of matching any other person are 1-(356/365)^9.

Maybe.

But I have no clue how to calculate this for three people matching.
