I need to do this calculation to save the earth from being hit by a large asteroid, so quick help would be appreciated. If we survive, I'll give you rep.

Hey Rain Man,

That's the hypergeometric distribution. Excel has a function hypergeomdist() for that.

Here's the Wolfram link on the hypergeometric distribution:
