Hi  

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



       A	B	C	Total

Male	10	7	6	23

Female	11	9	4	24

Total	21	16	10	47





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



Find the probability that the student was female GIVEN they got a 'B'.

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

P =  = 9/16
