Poker probability The "nCr" function on most scientific calculators can be used to calculate hand frequencies; entering with and , for example, yields formula_2 as above. The royal flush is a case of the straight flush. It can be formed 4 ways (one for each suit), giving it a probability of 0.000154% and odds of 649,739 : 1. When ace-low straights and ace-low straight flushes are not counted, the probabilities of each are reduced: straights and straight flushes each become 9/10 as common as they otherwise would be. The 4 missed straight flushes become flushes and the 1,020 missed straights become no
Pick a Partner Poker Pick a Partner Poker Pick a Partner is a variant of draw poker which requires players to work as a team. It must be played with an even number of players (at least four) because it requires them to work in pairs and combine their hands. Everyone is dealt a five-card poker hand face down, then chooses one card each to expose. The player with the highest hand selects another player as a partner. They are not obliged to show their strongest card. Then the next available player with the highest card picks their partner, until everyone is paired up.
