The answer is four. Each ace or king of diamonds or clubs will make you a full house. Your winning percentage is thus 4 / 46 = 8.7%.

Suppose you hold ace-king of hearts. On the board are an ace, a king, a seven and a four, all in spades. The likelihood is high that with your top two pairs, you lie behind behind an opponent who already has a flush. The only thing that could help you to win this hand is a full house. How many outs do you have? The probability that you will make your straight on the river is therefore 8 / 46 = 17.4%. But because you do not know these cards, you have to consider these cards as well for this calculation. So you have 8 outs out of a total of 46 cards. The answer is eight. Four jacks and four sixes are among the unknown cards. The probability that one of those eight cards will be shown on the river can be calculated easily. 46 unknown cards remain in the game: from the 52 cards, two are your hole cards and four of them are on the board. Of course, other players also hold cards in their hands, and some cards are in the “muck”. Suppose your hole cards are 9 and 8 of hearts. On the board are an ace, a ten, a seven and a three in different colors. A jack or a six would help you to make your straight, which will be very likely the winning hand. How many outs do you have?

After the flop, it is very easy to exactly calculate the probability to win. Typically, we speak about outs after the flop. But what do “Outs” mean? The principle of outs is quite simple. Any card that helps you to shape the winning hand is called an out. For sure you will already have heard of the term “outs” in relation with playing poker.
