Make a table of the joint relative frequencies and marginal relative frequencies. Round to the nearest hundredth where appropriate. The table has been started for you.$\newline$Has a orivers Lifense$\newline$\begin{tabular}{|c|c|c|c|c|}$\newline$\hline & & \multicolumn{$3$}{|c|}{ Has a Driver's License } \\$\newline$\hline \multirow{$4$}{*}{ Has a Job } & & Yes & No & Total \\$\newline$\hline & Yes & & $0$.$12$ & \\$\newline$\hline & No & & & \\$\newline$\hline & Total & $0$.$68$ & & $1$ \\$\newline$\hline$\newline$\end{tabular}$\newline$b. If you are given that a $17$ -year-old has a job, what is the probability that the $17$ -year-old also has a driver's license? Divide a joint relative frequency by a marginal relative frequency to find the answer. Round your answer to the nearest hundredth.$\newline$c.
