Answer 1

To find:

Find the probability that the student was male AND got a "B".

SOlution:

There are total of 50 students. If we select one student at random then there are 3 students who are male and got a B. So, the required probability is:

`P(M\cap B)=(3)/(17)=0.176`

Thus, the answer is 0.176.
