As a professional in the field of probability and statistics, particularly in the context of poker, I can provide a detailed explanation of the odds of hitting a set on the flop.
In poker, a set is a hand that consists of three cards of the same rank. When you have a pocket pair, which means you are holding two cards of the same rank, the flop is the first set of three community cards that are dealt face up on the table. The odds of hitting a set on the flop with a pocket pair are a fundamental concept in poker strategy.
To calculate the odds, we need to consider the total number of possible outcomes and the number of favorable outcomes. In a standard 52-card deck, there are 52 cards, and when you have a pocket pair, there are three remaining cards of the same rank that could complete your set.
The total number of possible outcomes for the flop is calculated by considering the number of ways to choose 3 cards from the remaining 50 cards (since you already have a pair in your hand). This is a combination, which is calculated as follows:
\[ \text{Total Outcomes} = \binom{50}{3} \]
The binomial coefficient \( \binom{n}{k} \) represents the number of ways to choose \( k \) items from \( n \) items without regard to order. For our case:
\[ \binom{50}{3} = \frac{50 \times 49 \times 48}{3 \times 2 \times 1} = 19600 \]
Now, let's calculate the number of favorable outcomes. Since there are three cards that can complete your set, and there are 50 cards left in the deck, the number of ways to hit a set on the flop is:
\[ \text{Favorable Outcomes} = \binom{3}{1} \times \binom{47}{2} \]
The first term \( \binom{3}{1} \) represents the number of ways to choose one of the three cards that will complete your set, and the second term \( \binom{47}{2} \) represents the number of ways to choose the remaining two cards from the 47 other cards in the deck.
\[ \binom{3}{1} = 3 \]
\[ \binom{47}{2} = \frac{47 \times 46}{2 \times 1} = 1081 \]
So, the total favorable outcomes are:
\[ 3 \times 1081 = 3243 \]
The odds of hitting a set on the flop are then the ratio of favorable outcomes to total outcomes:
\[ \text{Odds of Hitting a Set} = \frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{3243}{19600} \]
To express this as a ratio, we can simplify the fraction:
\[ \frac{3243}{19600} \approx \frac{1}{6.04} \]
This means that the odds of hitting a set on the flop with a pocket pair are approximately 1 in 6, or about 1 to 5.96. It's important to note that these odds are not the same as the odds against hitting a set, which would be the complement of the probability:
\[ \text{Odds Against Hitting a Set} = \frac{\text{Total Outcomes} - \text{Favorable Outcomes}}{\text{Favorable Outcomes}} = \frac{19600 - 3243}{3243} \approx 5.96 \]
So, the odds against hitting a set are approximately 5.96 to 1.
In conclusion, the odds of hitting a set on the flop with a pocket pair are better than the initial statement suggests. While it is true that the odds against hitting a set are 7 to 1, the actual odds of hitting a set are closer to 1 to 6, or approximately 1 in 6. This is a critical distinction in poker strategy, as understanding the true odds can significantly impact your decision-making process.

You will indeed hit a set on the flop with a pocket pair approximately 1 in 8 times, which would technically equate to odds of 1 to 7 as opposed to 7 to 1. The 7 to 1 odds are the odds AGAINST hitting the set.
