Chapter 13, Problem 12GRFC

To determine

To calculate; to find the probability of given outcome, when a die is rolled.

Answer to Problem 12GRFC

Solution: $P\left(vowels\right)=\frac{1}{5}or20\%$

Explanation of Solution

There are 4 vowels on the dice: A, E, I and O

Since the dice is 20 sided, therefore number of possible outcomes is 20

  $\begin{array}{l}P\left(vowels\right)=\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}\\ =\frac{4}{20}=\frac{1}{5}\end{array}$
