The required probability is, $\frac{5}{12}\approx 0.42$
We know that from the provided table, $P\left( \text{selecting a man among from the adult male population} \right)=\frac{\text{number of married men}}{\text{number of persons divorced}}$ Thus, \begin{align} & P\left( \text{selecting a man among from the adult male population} \right)=\frac{10}{24} \\ & =\frac{5}{12} \\ & \approx 0.42 \end{align}
