Hey guys, I was wondering if anybody knows the combined odds (or how to calculate them) of flopping any of the following?

Top Pair good kicker or better
Nut backdoor flush draw
Any straight draw
Any flush draw

It is necessary to use combinatorics for such calculations, namely the number of combinations.

For example, for the case when we have two suited pocket cards, the probability that on the flop will be a flush draw:

P = C (2, 11) * C (1, 39) / C (3, 50) = 55*39/19600 = 0.1094 or 10.94%

Oh wow, thanks for explaining, been awhile since I did this ^_^

Is there any combinatorics calculator website you are aware of?
