Texas Holdem Flop Occurrence Probabilities
The occurrence probabilities of the different types of Holdem flops can be a little confusing because about half of the possible flops contain more than one of the types that are shown. Since each set of properties is counted on its own and compared individually to the 22,100 possible three card combinations, the total of all the various flops far exceeds the number of possible combinations.
The typical flop shown in the illustration above is good example. This one contains two of our properties. These are "Two High Card Denominations" and "Two Cards Suited". This particular flop would then be counted twice - once for each of the two categories contained.
"High Cards" here are 10, J, Q, K, and Ace.
NOTE: All the flop type calculations are based on a complete 52 card deck with no hands dealt.
