Introduction

Probability is a fundamental concept in mathematics that deals with the likelihood of an event occurring. In this article, we will explore the concept of probability in trials and how it can be used to solve problems. We will use a spinner as an example to illustrate the concept of probability and how it can be used to determine the number of trials performed.

The Spinner Experiment

A spinner is a circular object with different colored sections, each representing a possible outcome. In this experiment, the spinner landed on red 6 times. The probability of landing on red is given as $\frac{1}{8}$ . We need to determine the number of trials performed.

Understanding the Probability of Landing on Red

The probability of landing on red is given as $\frac{1}{8}$ . This means that out of every 8 trials, 1 trial will result in landing on red. To find the number of trials performed, we need to use the concept of probability.

Using the Concept of Probability to Solve the Problem

Let's assume that the number of trials performed is x. We know that the probability of landing on red is $\frac{1}{8}$ . This means that the number of times the spinner landed on red is equal to the probability of landing on red multiplied by the number of trials performed.

Mathematically, this can be represented as:

Number of times landed on red = Probability of landing on red x Number of trials performed

Substituting the values, we get:

6 = $\frac{1}{8}$ x x

To solve for x, we can multiply both sides of the equation by 8:

48 = x

Therefore, the number of trials performed is 48.

Conclusion

In this article, we used the concept of probability to solve a problem involving a spinner. We found that the number of trials performed is 48. This problem illustrates the importance of understanding probability in mathematics and how it can be used to solve real-world problems.
