Chapter 11.8, Problem 2E

To determine

To find complement of rolling an odd number on a number cube.

Answer to Problem 2E

The complement of rolling an odd number on a number cube is $\frac{1}{2}$ or rolling an even number on the cube.

Explanation of Solution

Given information:

An odd number is rolled on a number cube.

There are 3 odd numbers on fair number cube having a total of 6 number

The probability of rolling an odd number is $\frac{3}{6}=\frac{1}{2}$

The compliment of probability is $\text{1}-\frac{1}{2}=\frac{1}{2}$

Hence,verbally it can be explained as compliment of rolling an odd number is rolling an evennumber on the cube number.
