# Chapter 10 - Section 10.7 - Probability - Exercise Set - Page 1118: 3

The required probability is, $\frac{62}{141}\approx 0.51$

#### Work Step by Step

We know that from the provided table, $P\left( \text{female} \right)=\frac{\text{number of persons who are females}}{\text{total number of U}\text{.S adults}}$ Thus, \begin{align} & P\left( \text{female} \right)=\frac{124}{242} \\ & =\frac{62}{141} \\ & \approx 0.51 \end{align}
