Hi  

A test was given to a group of students. The grades and gender are summarized below

        A	B	C	Total

Male	19	20	2	41

Female	6	15	17	38

Total	25	35	19	79

If one student is chosen at random from those who took the test,

Find the probability that the student got a 'B' GIVEN they are male

P(A|B) = P(A and B)/P(B)

P(B | M) =  = 20/35
