Two way tables questions and answers

The following two-way table displays information about favorite sports cars that resulted from a survey given to all students at Shore High School.

\(\begin{array}{|c|c|}\hline & \text{Corvette (C)} & \text{Porsche (P)} & \text{Ferrari (F)} & \text{Total} \\ \hline \text{Boys (B)} & 90 & 60 & 120 & 270 \\ \hline \text{Girls (G)} & 110 & 141 & 79 & 330 \\ \hline \text{Total} & 200 & 201 & 199 & 600 \\ \hline \end{array}\)

What is the probability that a randomly selected student from this school is a boy?

Use the two-way table of data from another student survey to answer the following question.

\(\begin{array}{|c|cc|c|} \hline &Like\ Aerobic&Exercise\\ \hline Like\ Weight\ Lifting&Yes&No&Total\\ \hline Yes & 7&14&21 \\ \hline No& 12&7&19\\ \hline Total&19&21&40\\ \hline \end{array}\)
What is the marginal relative frequency of students surveyed who like weight lifting?

Use the two-way table of data from another student survey to answer the following question.
\(\begin{array}{|c|cc|c|} \hline &Like\ Aerobic&Exercise\\ \hline Like\ Weight\ Lifting&Yes&No&Total\\ \hline Yes & 7&14&21 \\ \hline No& 12&7&19\\ \hline Total&19&21&40\\ \hline \end{array}\)
Find the conditional relative frequency that a student likes to lift weights, given that the student likes aerobics.
