In general, to find the probability of certain outcomes, you have to follow these steps:

1) Find the number of flops/boards that contain that outcome, and

2) Divide that by the total number of flops/boards.

For example, let's say you want to find the probability of flopping a set, full house, or four of a kind given that you have been dealt AA. The number of flops with a single ace is:

C(2,1) * C(48,2) = 2256

The number of flops with two aces is:

C(2,2) * C(48,1) = 48

The total number of flops is:

C(50, 3) = 19600

So, the probability of flopping a set, full house, or four of a kind is (2256 + 48)/19600 = 0.1176 or 11.76%.

If you need more information on combinations (C(x, y) is the number of ways to choose y objects out of x objects) try searching on Google.

Hope that helps.
