Chance of the board pairing
He we go.
Very simple calculation:
Calculate the chance of board NOT pairing:
First card is irrelevant. Say A.
Second card must not be an A so can only be 16 out of the 19 left.
Third card is 12/18.
Fourth card is 8/17.
Fifth is 4/16.
Give 16/19 * 12/18 *8/17 * 4/16 = 0.066
So chance of pairing = 1-0.066 = 0.954 or 95.4%.
Next I need to calculate what the chances are of winning if you have a PP.
