The Odds Behind Every Hand
Card games reward players who understand probability — the odds of a particular hand, a favorable draw, or a winning bid are all fixed numbers that skilled players lean on more than luck. These ten calculators cover the probability math behind popular card games.
How Rare Is Your Hand, Really?
A five-card poker hand drawn from a standard 52-card deck has 2,598,960 possible combinations. Some hands players consider "good" are actually fairly common; others are vanishingly rare.
| Hand | Probability |
|---|---|
| One Pair | 42.3% |
| Two Pair | 4.75% |
| Three of a Kind | 2.11% |
| Straight | 0.39% |
| Flush | 0.197% |
| Full House | 0.144% |
| Four of a Kind | 0.024% |
| Straight Flush | 0.0014% |
Quick tip: a straight only needs five sequential ranks regardless of suit, a much less restrictive condition than a flush needing all five cards to share a suit — which is exactly why straights beat flushes in frequency but flushes outrank straights in most game rules.
Run specific scenarios through the Poker Odds Calculator or Texas Hold'em Equity Calculator. For contract bridge, the Bridge Point Count Calculator totals high-card points for standard bidding conventions, and the Deck Shuffle Randomness Calculator estimates how many riffle shuffles fully randomize a deck.
