Chapter 12.7, Problem 36PPE

(a)

To determine

To find: The experimental probability that a randomly selected worker at that company walks to work.

Answer to Problem 36PPE

The experimental probability that a randomly selected worker at that company walks to work is $\frac{17}{80}$ .

Explanation of Solution

Given:

Out of 80 workers surveyed at a company, 17 walk to work.

Calculation:

Find the experimental probability that a randomly selected worker at that company walks to work.

  $P=\frac{17}{80}$

Therefore, the experimental probability that a randomly selected worker at that company walks to work is $\frac{17}{80}$ .

(b)

To determine

To find: The number of the $3600$ workers at the company walk to work.

Answer to Problem 36PPE

The number of workers who walk to work are $765$ .

Explanation of Solution

Given:

Out of 80 workers surveyed at a company, 17 walk to work.

Calculation:

Find the number of workers who walk to work as follows.

  $\begin{array}{c}N=\frac{17}{80}\times 3600\\ =765\end{array}$

Therefore, the number of workers who walk to work are $765$ .
