Which college math course would best help my poker game?

[img]/images/graemlins/wink.gif[/img] a course on counting isnt about counting small numbers, its about counting the number of different ways to do something and stuff like that. for example, how many different ways can you make a flush? thats a counting problem. or prove that in every five cards there has to be atleast 2 of 1 suit (direct pigeon hole principle). it has lots of applications to poker.
