$\begin{gathered} P(No∣\text{ with child under 18\rparen}=\frac{#people\text{ said ''No'' and has a child under 18}}{#\text{ total people with child under 18}} \\ \\ P(No∣\text{ with child under 18\rparen}=\frac{240}{530} \\ \\ P(No∣\text{ with child under 18\rparen}=0.4528 \end{gathered}$Then, the probability that a randomly chosen person from this group said "no" given that the person has a child under 18 years old is 0.4528
