Hi 



In retrospect, Description did indicate those getting As... as the "Universe"

In That case, probability would be: P = 17/19. 



        A	B	C	Total

Male	2	3	6	11

Female	highlight%2817%29	7	13	37

Total	highlight%2819%29	10	19	48

P(A, Not Male) = 17/48

Giving a test to a group of students, the grades and gender are summarized below
........A B C Total
Male 2 3 6 11
Female 17 7 13 37
Total 19 10 19 48
If one student is chosen at random,
Find the probability that the student was NOT a male that got a "A"
-----
"got an A" is the universe
"not a male" is success
-----
P(not a male " | got an A} = P(not a male AND got an A)/P(got an A)
= (17/48)(19/48) = 7/19
