Say we have A5s and want to know the chances that the board flops a gutshot.
Whats the chance we flop 32x 42x or 43x with a5s?

probability was the area of math i didnt study

I imagine this is a simple combinatorics problem. Havn't done this in a while, but you represent all possible flops as the sample space, there are 22,100 of them i think. Then represent flopping a gutshot as an event.

The formula will look like P(A) = A/S, where P(A) is probably of the event of flopping a gutshot, and A=size of event, S=size of sample space.

ill use combinations instead of permutations, so order doesn't matter.

the sample space of all flops is 52!/(3!x49!)=22,100

Can't figure out the event of flopping a gutshot right now.

Your math is weird Stroggoz. That's some event horizon mathematics.

117600 different flops

sure, its 117600 different flops if order matters, but it doesn't. there is no difference between AdKdTs and TsKdAd. there are 6 ways to order every flop, and therefore you divide 117600 by 6 and get 22,100. well actually, you dont since i wasn't counting 2 cards in my hand

Whatever that is. This excludes flopping straights.

Researchers used brain scans to show that when straight men looked at pictures of women in bikinis, areas of the brain that normally light up in anticipation of using tools, like spanners and screwdrivers, were activated.
