Answer
The required probability is, $\frac{11}{242}\approx 0.05$
Work Step by Step
We know that from the provided table,
$ P\left( \text{widowed female} \right)=\frac{\text{number of widowed females}}{\text{total number of U}\text{.S adults}}$
Thus,
$\begin{align}
& P\left( \text{widowed female} \right)=\frac{11}{242} \\
& \approx 0.05
\end{align}$
