Introduction

In this article, we will explore a game of chance that involves two spinners, each with different numbers of sections. The first spinner, labeled as $A$ , has four sections with numbers 2, 4, 6, and 8. The second spinner, labeled as $B$ , has three sections with numbers 1, 3, and 5. Players spin both spinners and add the numbers together to determine the outcome of the game. In this article, we will complete the possibility table for this game and discuss the different outcomes.

The Possibility Table

To create the possibility table, we need to consider all the possible combinations of numbers that can be obtained by spinning both spinners. Since spinner $A$ has four sections and spinner $B$ has three sections, there are a total of $4 \times 3 = 12$ possible combinations.

Spinner $A$	Spinner $B$	Sum
2	1	3
2	3	5
2	5	7
4	1	5
4	3	7
4	5	9
6	1	7
6	3	9
6	5	11
8	1	9
8	3	11
8	5	13

Analyzing the Possibility Table

From the possibility table, we can see that the possible sums range from 3 to 13. The most common sum is 7, which occurs three times. The least common sum is 3, which occurs only once.

Calculating the Probability of Each Outcome

To calculate the probability of each outcome, we need to divide the number of times each sum occurs by the total number of possible combinations, which is 12.

Sum	Number of Occurrences	Probability
3	1	1/12
5	2	2/12
7	3	3/12
9	3	3/12
11	2	2/12
13	1	1/12

Conclusion

In this article, we have completed the possibility table for a game of chance involving two spinners. We have analyzed the table and calculated the probability of each outcome. The results show that the most common sum is 7, which occurs three times, and the least common sum is 3, which occurs only once. This game of chance can be used to teach students about probability and the concept of independent events.

Understanding the Concept of Independent Events

In this game, the spin of each spinner is an independent event. The outcome of one spinner does not affect the outcome of the other spinner. This is because the spin of each spinner is a random event, and the outcome is determined by chance.

The Importance of Probability in Real-Life Situations

Probability is an important concept in many real-life situations. It is used in fields such as medicine, finance, and engineering to make predictions and decisions. In the game of chance we have discussed, probability is used to calculate the likelihood of each outcome. This can be applied to many real-life situations, such as predicting the weather, calculating the risk of a disease, or determining the probability of a stock price increasing.

Real-Life Applications of Probability

Probability has many real-life applications. Some examples include:

Insurance: Insurance companies use probability to calculate the risk of a person getting sick or injured.
Finance: Financial institutions use probability to calculate the risk of a stock price increasing or decreasing.
Medicine: Doctors use probability to calculate the risk of a patient getting a disease.
Engineering: Engineers use probability to calculate the risk of a machine failing.

Conclusion

In conclusion, the game of chance involving two spinners is a useful tool for teaching students about probability and the concept of independent events. The possibility table and probability calculations provide a clear understanding of the different outcomes and their likelihood. This game can be used to teach students about probability and its real-life applications.

We completed the possibility table and calculated the probability of each outcome. In this article, we will answer some frequently asked questions about the game and provide additional insights.

Q&A

Q: What is the probability of getting a sum of 7?

A: The probability of getting a sum of 7 is 3/12, which simplifies to 1/4 or 25%.

Q: What is the most common sum in the game?

A: The most common sum in the game is 7, which occurs three times.

Q: What is the least common sum in the game?

A: The least common sum in the game is 3, which occurs only once.

Q: How many possible combinations are there in the game?

A: There are 12 possible combinations in the game, which are obtained by multiplying the number of sections on each spinner.

Q: What is the probability of getting a sum of 13?

A: The probability of getting a sum of 13 is 1/12, which is the least common sum in the game.

Q: Can you explain the concept of independent events in the game?

A: Yes, the spin of each spinner is an independent event. The outcome of one spinner does not affect the outcome of the other spinner. This is because the spin of each spinner is a random event, and the outcome is determined by chance.

Q: How can probability be applied in real-life situations?

A: Probability can be applied in many real-life situations, such as predicting the weather, calculating the risk of a disease, or determining the probability of a stock price increasing.

Q: What are some real-life applications of probability?

A: Some real-life applications of probability include insurance, finance, medicine, and engineering.

Q: Can you provide an example of how probability is used in insurance?

A: Yes, insurance companies use probability to calculate the risk of a person getting sick or injured. For example, if an insurance company has a policy that covers a person for a certain amount of money in the event of a car accident, the company will use probability to calculate the likelihood of the person being involved in a car accident.

Q: Can you provide an example of how probability is used in finance?

A: Yes, financial institutions use probability to calculate the risk of a stock price increasing or decreasing. For example, if a financial institution is considering investing in a particular stock, it will use probability to calculate the likelihood of the stock price increasing or decreasing.

Q: Can you provide an example of how probability is used in medicine?

A: Yes, doctors use probability to calculate the risk of a patient getting a disease. For example, if a doctor is considering prescribing a medication to a patient, it will use probability to calculate the likelihood of the patient responding to the medication.

Q: Can you provide an example of how probability is used in engineering?

A: Yes, engineers use probability to calculate the risk of a machine failing. For example, if an engineer is designing a machine, it will use probability to calculate the likelihood of the machine failing and to determine the necessary safety measures to prevent failure.
