Chapter 13.3, Problem 57AYU

To determine

To find: The probability if the golf ball is white or green.

Answer to Problem 57AYU

$\frac{17}{20}$

Explanation of Solution

Given:

A golf ball is selected at random from a container. If the container has 9 white balls, 8 green balls, and 3 orange balls.

Formula Used:

$P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}$

Calculation:

The container has 9 white balls, 8 green balls, and 3 orange balls.

$P\left(white or green\right)=P\left(white\right)+P\left(Green\right)$

$P\left(E\right)=\frac{n\left(E\right)}{n\left(S\right)}$

$P\left(White\right)=9/20$

$P\left(Green\right)=8/20$

$P\left(white or green\right)=\frac{9+8}{20}=\frac{17}{20}$
