Chapter 5, Problem 9PT

To determine

To find: The probability that randomly chosen individual is either never married or a woman.

Answer to Problem 9PT

The probability is 0.66.

Explanation of Solution

Given:

Probability of woman = 0.52

Probability of never married = 0.25

Probability of women and never married = 0.11

Calculation:

The probability that randomly chosen individual is either never married or a woman can be calculated as:

  $\begin{array}{c}P\left(\text{Never married or woman}\right)=P\left(\text{Never married}\right)+P\left(\text{woman}\right)-P\left(\text{Never married and Woman}\right)\\ =0.25+0.52-0.11\\ =0.66\end{array}$

Thus, the required probability is 0.66.

Hence, the correct option is (b).
