Introduction

Rolling a die is a classic probability experiment that has been studied extensively in mathematics. A standard die has six faces, each with a different number of dots ranging from 1 to 6. In this article, we will explore the probabilities associated with rolling a die and calculate the probability of getting a specific number. We will focus on finding the probability of getting a 5 when a die is rolled one time.

The Sample Space

Before we can calculate the probability of getting a 5, we need to understand the sample space of the experiment. The sample space is the set of all possible outcomes of the experiment. In this case, the sample space consists of the six possible outcomes: 1, 2, 3, 4, 5, and 6.

The Probability of Getting a 5

To calculate the probability of getting a 5, we need to use the formula for probability:

P(A) = Number of favorable outcomes / Total number of outcomes

In this case, the number of favorable outcomes is 1 (getting a 5), and the total number of outcomes is 6 (the six possible outcomes of the experiment).

P(5) = 1/6

Interpretation of the Result

The probability of getting a 5 when a die is rolled one time is 1/6 or approximately 0.167. This means that if you were to roll a die 100 times, you would expect to get a 5 approximately 16-17 times.

Conclusion

In this article, we calculated the probability of getting a 5 when a die is rolled one time. We used the formula for probability and found that the probability is 1/6 or approximately 0.167. This result can be applied to various real-world situations where probability is involved.
