If anyone can tell me what the odds of the board in holdem double pairing is , I would sure be very thankfull. [/ QUOTE ] 5-card board, 2-pair or full house on board, but not quads: [ C(13,2)*C(4,2)*C(4,2)*44 + 2*C(13,2)*C(4,3)*C(4,2) ] / C(52,5) = 4.9%. 1st line is for 2-pair only: C(13,2) is the number of ways to choose ranks of 2-pair. C(4,2) is the number of possible pairs for each rank. 44 is the number of ways to pick the unpaired card. 2nd line is for full house: 2*C(13,2) is the number of ways to choose rank of trips and pair. C(4,3) is the number of ways to choose the 3 matching for full house. C(4,2) is the number of ways to choose the 2 matching for full house. C(52,5) = total number of board card combinations. |
