The table shows the results of a survey of college students. Find the probability that a student’s first class of the day is a humanities class, given the student is male. Round to the nearest thousandth.

Male Female

Humanities 70 80
Science 50 80
Other 60 70

A. 0.171
B. 0.467
C. 0.269
D. 0.389

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have the total number of male students = 70+50+60 = 180

So, the total number of outcomes = 180

Total number of male students who take humanities class = 70

Now, the probability = 70/180 = 0.388 ≈ 0.389

Thus, the probability that a student is taking a humanities class, given the student is male, is 0.389 option (D) is correct.
