Possible solution: A survey could be asking the girls and boys in your class do you own a pet. For a class of 40 students, the results could then be:
\(\begin{array}{|c|c|c|} \hline &Boy&Girl&Total\\ \hline Yes & 5&10&15 \\ \hline No& 14&11&25\\ \hline Total&19&21&40 \\ \hline \end{array}\)
Dividing each cell of the table by 40 will then give the marginal and joint frequencies:
\(\begin{array}{|c|c|c|} \hline &Boy&Girl&Total\\ \hline Yes & 0.125&0.250&0.375 \\ \hline No& 0.35&0.275&0.625\\ \hline Total&0.475&0.525&1 \\ \hline \end{array}\)
