Default Re: probabilty of ATC opponent flopping flush draw

Well, it's a weird question but I guess if you really want the answer the easiest way would be through combinations.

With 48 cards remaining and 10 cards of his suit, there are 10*9 / 2 = 45 combinations of two cards on the flop that could hit. Multiply this by the remaining 38 non-suited cards and you get 1710 possible flops where he has a flush draw. Divide this by 48c3 = 17296 total possible flops, and you get 0.0989 probability.

I'm not really sure why you stipulated that you have one card of his suit, but that's the answer assuming such a condition.
