Default Re: Need help with some flop probability calcs

There are 50 choose 3 = 50*49*48/(3*2*1) = 19600 flops. You can flop a straight that is ace-high, king-high, queen-high, or jack-high. For each possible straight, there are 4 choices for the suit of each card, except that you should subtract off the straight flush. So, the total number of flopped straights is 4*(4*4*4-1) = 252. The probability of flopping a straight is 252/19600.
