A-5 Dealt Hand Probabilities

From LowballWiki

Jump to: navigation, search

These tables show the probability of being dealt an A-5 hand of the specified strength (5-high, 6-high, etc.) for a variety of different hand sizes and wild card choices. The full list is available at Durago Bill's Lowball Poker Probabilities. Bill Butler wrote the program to generate this data and ran the calculations.

Note that the hands being compared are always 5-card A-5 lowball hands, even if the table is for a deal containing more cards.

The median hand is thus a very rough K-high. The median is the "1299480th" hand, while the first pair is hand 1,317,888. Each rank comes in 1024 possibilities due to the suit assignments of the 5 cards. (1024=5^4.) So the median hand is the 18th worst K-high. Counting down from KQJT9 gives us KQJ87 (unless I made an off-by-one error or two or three.)
