A question that has probably been asked a million times .....

[BugSplatt]

Can someone tell me the math involved in this common everyday occurence. You have two suited cards, flop two suited cards - what is the formulation that stipulates that you have a 34.97% chance of hitting one of your flush cards on turn or river?

I know, for example, how to calculate the chance of flopping a flush: ((11/50)*(10/49)*(9/48)) = 0.84
but my statistical knowledge ends there.

Thanks in advance,
