What Are the Odds of Flopping a Set with a Pocket Pair?
When you hold a pocket pair, you flop a set about 11.76% of the time — roughly 1 in 8.5. That is the number behind the 'set-mining' rule of thumb.

| Measured as | Probability | Odds | Per 100 hands |
|---|---|---|---|
| You flop a set, given you hold a pocket pairheadline | 11.8% | 1 in 8.51 | — |
| Per random hand dealt (dealt a pair and flop it) | 0.692% | 1 in 145 | 0.69 |
What we measured
Flopping a set means your pocket pair improves to three of a kind on the flop — one of your two remaining cards of that rank appears among the three flop cards. This figure is conditional on already holding the pocket pair. We also show the chance across a random hand (being dealt a pair and then flopping the set).
How it was calculated
Exact combinatorics: 1 minus C(48,3) / C(50,3) — the chance the flop misses both of your remaining set cards.

Frequently asked questions
What are the odds of flopping a set?+
With a pocket pair, you flop a set about 11.76% of the time — 1 in 8.5. This is the foundation of set-mining: you need enough implied odds to justify calling with a small pair to flop that roughly 12%.
How often will I flop a set overall?+
Counting the chance you are even dealt a pocket pair first, you flop a set about 1 in 145 hands overall — around 0.69% of all deals.
Is 7.5 to 1 the right set-mining number?+
Yes. 1 in 8.5 to flop a set is about 7.5-to-1 against, which is why the classic set-mining guideline asks for implied odds of roughly 10-to-1 or better before calling a raise with a small pocket pair.
