In order to determine the probability of a random selected student to be a men, we need to divide the number of men by the number of all the students in the class. We have:
[tex]\begin{gathered} p(\text{men)}=\frac{56}{28+56} \\ p(\text{men)}=\frac{56}{84} \\ p(\text{men)}=0.67 \end{gathered}[/tex]The probability of a random student being a man is approximately 67%.
