Re: A pair in the flop
[ QUOTE ]
1. The probability the flop has a pair in it. The flop must come in the form of (x,x,z), therefore,
13*3*48/c(52,3)=.0847%
Thats 13 ways to choose the first x, 3 ways to choose the second and 48 other cards for the third.

Almost. For each rank, there are (4 choose 2) = 6 possible ways to make a pair. Each of those goes with 48 possible 3rd cards. So it should be 13*6*48/(52 choose 3) = .1694.
Don't have time now to check the other part.
