A Basketball Player Shoots 40 Free Throws And Makes 28 Of Them.1. What Is The Experimental Probability Of Free Throws Made?2. What Would The Theoretical Probability Be?
Introduction
Probability is a fundamental concept in mathematics that helps us understand the likelihood of an event occurring. In this article, we will explore the concept of probability through a real-life scenario involving a basketball player's free throw shots. We will calculate both the experimental and theoretical probability of the player making free throws.
Experimental Probability
Experimental probability is a measure of the likelihood of an event occurring based on repeated trials or experiments. In this case, the basketball player shoots 40 free throws and makes 28 of them. To calculate the experimental probability, we divide the number of successful trials (making free throws) by the total number of trials (total free throws shot).
Experimental Probability Formula
Experimental Probability = (Number of Successful Trials) / (Total Number of Trials)
Experimental Probability Calculation
Experimental Probability = 28 / 40 Experimental Probability = 0.7 Experimental Probability = 70%
Therefore, the experimental probability of the basketball player making free throws is 70%.
Theoretical Probability
Theoretical probability, also known as classical probability, is a measure of the likelihood of an event occurring based on the number of favorable outcomes divided by the total number of possible outcomes. In this case, we assume that each free throw shot has an equal chance of being made or missed.
Theoretical Probability Formula
Theoretical Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes)
Theoretical Probability Calculation
Since each free throw shot has two possible outcomes (made or missed), the total number of possible outcomes is 2. The number of favorable outcomes is the number of free throws made, which is 28.
Theoretical Probability = 28 / 2 Theoretical Probability = 0.7 Theoretical Probability = 70%
Therefore, the theoretical probability of the basketball player making free throws is also 70%.
Comparison of Experimental and Theoretical Probability
In this scenario, both the experimental and theoretical probability of the basketball player making free throws is 70%. This is not a coincidence. When the number of trials is large, the experimental probability tends to approach the theoretical probability. This is known as the law of large numbers.
Real-Life Implications
Understanding probability is crucial in many real-life situations, such as:
- Sports: Coaches and players use probability to make informed decisions about game strategy, such as when to take a shot or when to pass the ball.
- Finance: Investors use probability to make informed decisions about investments, such as the likelihood of a stock increasing in value.
- Insurance: Insurance companies use probability to determine the likelihood of an event occurring, such as a car accident or a natural disaster.
Conclusion
In conclusion, the experimental and theoretical probability of a basketball player making free throws is 70%. This scenario illustrates the concept of probability and its real-life implications. Understanding probability is essential in many fields, including sports, finance, and insurance.

Q: What are some real-life implications of probability?
A: Probability is used in many real-life situations, such as sports, finance, and insurance.
Q: Can you give an example of how probability is used in sports?
A: Yes, in basketball, coaches and players use probability to make informed decisions about game strategy, such as when to take a shot or when to pass the ball. For example, if a player has a 70% chance of making a free throw, the coach may decide to have them shoot the free throw instead of passing the ball to another player.
Q: Can you give an example of how probability is used in finance?
A: Yes, investors use probability to make informed decisions about investments, such as the likelihood of a stock increasing in value. For example, if a stock has a 60% chance of increasing in value over the next year, an investor may decide to invest in the stock.
Q: Can you give an example of how probability is used in insurance?
A: Yes, insurance companies use probability to determine the likelihood of an event occurring, such as a car accident or a natural disaster. For example, if a car has a 10% chance of being involved in an accident over the next year, an insurance company may charge a higher premium for the car.
Q: What is the difference between probability and odds?
A: Probability is a measure of the likelihood of an event occurring, while odds are a measure of the ratio of the number of favorable outcomes to the number of unfavorable outcomes.
Q: Can you give an example of how probability and odds are used in sports?
A: Yes, in sports, probability and odds are used to determine the likelihood of a team winning a game. For example, if a team has a 60% chance of winning a game, the odds of them winning may be 3:1 or 2:1.
Q: Can you give an example of how probability and odds are used in finance?
A: Yes, in finance, probability and odds are used to determine the likelihood of a stock increasing in value. For example, if a stock has a 60% chance of increasing in value over the next year, the odds of it increasing in value may be 3:1 or 2:1.
Q: Can you give an example of how probability and odds are used in insurance?
A: Yes, in insurance, probability and odds are used to determine the likelihood of an event occurring, such as a car accident or a natural disaster. For example, if a car has a 10% chance of being involved in an accident over the next year, the odds of it being involved in an accident may be 10:1 or 5:1.
Conclusion
In conclusion, probability is a fundamental concept in mathematics that helps us understand the likelihood of an event occurring. It is used in many real-life situations, such as sports, finance, and insurance. Understanding probability is essential in making informed decisions about investments, game strategy, and risk management.
