Answer
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,
$\begin{align}
& P\left( \text{female} \right)=\frac{124}{242} \\
& =\frac{62}{141} \\
& \approx 0.51
\end{align}$
