A flush is a poker hand such as Q♣ 10♣ 7♣ 6♣ 4♣, which contains five cards of the same suit, not in rank sequence. It ranks above a straight and below a full house. We first pick one of four suits and then 5 cards from that suit. In other words, C(4,1)×C(13,5) = 5148. We then subtract the 4 possible Royal Flushes and the 36 possible Straight Flushes. Therefore, we have 5108 possible flushes, so the odds of getting a flush given a five card hand are 16627:33, or approximately 504:1.
