Chapter 13.3, Problem 21PPS

To determine

To explain:

The event with $33\%$ probability for each model

Answer to Problem 21PPS

The event that has $33\%$ probability of occurring the probability that the point is selected randomly is between $10$ and $20$ is equal to $33\%$ .

Explanation of Solution

Given information:

  

The number line consists of the three linear sections which is $10$ to $20$ , $20$ to $30$ ,and $30$ to $40$ . All of the segments are the equal size, the probability that the point is selected in segment is equal to $33\%$ since the segment represents $\frac{1}{3}$ of the total outcomes for the number line.

The event that has $33\%$ probability of occurring the probability that the point is selected randomly is between $10$ and $20$ is equal to $33\%$ .
