A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of 50 spins. She computes and graphs the relative frequencies for each number. Which of the following describes the probability distribution?

In the question "A spinner is divided into five sections numbered 1 through 5. Juana records the number the spinner lands on for each of 50 spins. She computes and graphs the relative frequencies for each number. Which of the following describes the probability distribution?" The correct answer is normal distribution.

Since the given graph is symmetrical about the center and looks like a bell shape, thus it represents a normal distribution.

The correct answer is:

This should be a uniform distribution.

Explanation:

Each of the sections labeled 1 through 5 would have the same probability of being landed on. This means that their relative frequencies should be nearly, if not exactly, the same.

When graphing this as a bar graph, it would be nearly level across the entire graph. This is called a uniform distribution, since the values are very close to (if not exactly) the same.
