Questions about outs

What is an out in poker?

A card still in the deck that takes you from behind to in front. A card that improves you but still loses is not an out, and one that only produces a split pot is not either.

How do I turn outs into a percentage?

Exactly: with two cards to come the chance of missing both is (47−outs)/47 × (46−outs)/46, and your equity is one minus that. As a shortcut, multiply outs by four from the flop and by two from the turn.

How many outs is a flush draw?

Nine, which is 35.0% from the flop and 19.6% from the turn. Thirteen cards of each suit exist and you can see four of them.

How many outs is an open-ended straight draw?

Eight, four cards at each end. That is 31.5% from the flop and 17.4% from the turn.

How many outs is a gutshot?

Four, one rank filling the middle of the run. That is 16.5% from the flop, which is not enough to call a half-pot bet on pot odds alone.

Why does the 2-and-4 rule overstate my equity?

Because the two cards are not independent, missing the turn removes a card from the deck and slightly changes the river probability. The shortcut ignores that, and the error grows with the number of outs: negligible at four, over five points at fifteen.
