Introduction

In basketball, a player's free throw average is a crucial statistic that measures their ability to score from the free throw line. A high free throw average indicates a player's accuracy and consistency in shooting free throws. In this article, we will explore the concept of a basketball player's free throw average and use it to calculate the chance of making less than 5 shots out of 9 free throws.

Understanding Free Throw Average

A basketball player's free throw average is calculated by dividing the number of free throws made by the total number of free throws attempted. For example, if a player makes 4 out of 10 free throws, their free throw average would be 40%. In this case, we are given that a basketball player has a free throw average of 42%. This means that the player makes 0.42 of their free throws, on average.

Calculating the Probability of Making Less Than 5 Shots

To calculate the probability of making less than 5 shots out of 9 free throws, we can use the binomial distribution formula. The binomial distribution formula is given by:

P(X = k) = (nCk) * (p^k) * (q^(n-k))

where:

P(X = k) is the probability of making k shots out of n free throws
n is the total number of free throws attempted (in this case, 9)
k is the number of shots made (in this case, less than 5)
nCk is the number of combinations of n items taken k at a time (also written as C(n, k) or "n choose k")
p is the probability of making a shot (in this case, 0.42)
q is the probability of missing a shot (in this case, 1 - 0.42 = 0.58)

Calculating the Probability of Making Less Than 5 Shots Using the Binomial Distribution Formula

To calculate the probability of making less than 5 shots out of 9 free throws, we need to calculate the probability of making 0, 1, 2, 3, and 4 shots, and then add these probabilities together.

Calculating the Probability of Making 0 Shots

P(X = 0) = (9C0) * (0.42^0) * (0.58^9) = 1 * 1 * 0.000145 = 0.000145

Calculating the Probability of Making 1 Shot

P(X = 1) = (9C1) * (0.42^1) * (0.58^8) = 9 * 0.42 * 0.4584 = 0.0181

Calculating the Probability of Making 2 Shots

P(X = 2) = (9C2) * (0.42^2) * (0.58^7) = 36 * 0.1764 * 0.2724 = 0.1443

Calculating the Probability of Making 3 Shots

P(X = 3) = (9C3) * (0.42^3) * (0.58^6) = 84 * 0.0735 * 0.1687 = 0.0943

Calculating the Probability of Making 4 Shots

P(X = 4) = (9C4) * (0.42^4) * (0.58^5) = 126 * 0.0309 * 0.0773 = 0.0241

Adding the Probabilities Together

To calculate the probability of making less than 5 shots out of 9 free throws, we add the probabilities of making 0, 1, 2, 3, and 4 shots together:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.000145 + 0.0181 + 0.1443 + 0.0943 + 0.0241 = 0.2812

Conclusion

In this article, we used the binomial distribution formula to calculate the probability of making less than 5 shots out of 9 free throws, given a basketball player's free throw average of 42%. We calculated the probability of making 0, 1, 2, 3, and 4 shots, and then added these probabilities together to get the final answer. The probability of making less than 5 shots out of 9 free throws is approximately 28.12%.

Introduction

In our previous article, we explored the concept of a basketball player's free throw average and used it to calculate the chance of making less than 5 shots out of 9 free throws. In this article, we will answer some frequently asked questions related to the topic.

Q: What is a free throw average, and how is it calculated?

A: A free throw average is a measure of a basketball player's ability to score from the free throw line. It is calculated by dividing the number of free throws made by the total number of free throws attempted. For example, if a player makes 4 out of 10 free throws, their free throw average would be 40%.

Q: How is the binomial distribution formula used to calculate the probability of making less than 5 shots?

A: The binomial distribution formula is used to calculate the probability of making k shots out of n free throws. In this case, we used the formula to calculate the probability of making 0, 1, 2, 3, and 4 shots, and then added these probabilities together to get the final answer.

Q: What is the probability of making less than 5 shots out of 9 free throws, given a basketball player's free throw average of 42%?

A: According to our previous article, the probability of making less than 5 shots out of 9 free throws is approximately 28.12%.

Q: How can I use the binomial distribution formula to calculate the probability of making more than 5 shots?

A: To calculate the probability of making more than 5 shots, you can use the binomial distribution formula to calculate the probability of making 6, 7, 8, and 9 shots, and then add these probabilities together.

Q: What is the difference between the binomial distribution and the normal distribution?

A: The binomial distribution is a discrete distribution that is used to model the number of successes in a fixed number of independent trials, each with a constant probability of success. The normal distribution, on the other hand, is a continuous distribution that is used to model the distribution of a continuous random variable.

Q: Can I use the binomial distribution formula to calculate the probability of making a certain number of shots in a game?

A: Yes, you can use the binomial distribution formula to calculate the probability of making a certain number of shots in a game, as long as you have the necessary information, such as the number of shots attempted and the probability of making each shot.

Q: How can I apply the concepts learned in this article to real-world situations?

A: The concepts learned in this article can be applied to real-world situations, such as calculating the probability of making a certain number of sales in a business, or the probability of winning a certain number of games in a sports competition.

Q: What are some common applications of the binomial distribution?

A: The binomial distribution has many common applications, including:

Calculating the probability of making a certain number of sales in a business
Calculating the probability of winning a certain number of games in a sports competition
Calculating the probability of making a certain number of errors in a manufacturing process
Calculating the probability of passing a certain number of students in a class

Q: How can I learn more about the binomial distribution and its applications?

A: You can learn more about the binomial distribution and its applications by reading books and articles on the topic, or by taking online courses or attending workshops.
