Chapter 11.1, Problem 22E

To determine

To calculate: to find the experimental probability that a student at the school has 2 or more pets.

Answer to Problem 22E

The experimental probability that a student at the school has 2 or more pets is $\frac{1}{3}$ .

Explanation of Solution

Given information: consider thehistogram provided in the question.

  

Calculation: to find the experimental probability that a student at the school has 2 or more pets sum of students who has 2 or more pets divide by total students.

Probability = $\begin{array}{l}\frac{5+1+4}{19+11+5+1+4}\\ \frac{10}{30}\\ \frac{1}{3}\end{array}$

Hence,

Thus ,The experimental probability that a student at the school has 2 or more pets is $\frac{1}{3}$ .
