Two-Way Frequency Table

On a certain day, a restaurant decided to record how many people sat outside and how many people sat inside. $$\begin{array}{|c|c|c|c|} \hline &\text{Inside}&\text{Outside}&\text{Total}\\ \hline \text{Men}&&34&\\ \hline \text{Women}&20&17&\\ \hline \text{Total}&51&&\\ \hline \end{array}$$
