The required probability is, $\frac{3}{242}\approx 0.01$
We know that from the given table, $P\left( \text{widowed male} \right)=\frac{\text{number of widowed males}}{\text{total number of U}\text{.S adults}}$ Thus, \begin{align} & P\left( \text{widowed male} \right)=\frac{3}{242} \\ & \approx 0.01 \end{align}
