Giving a test to a group of students, the grades and gender are summarized below

	A	B	C 	Total
Male	15	6	5 	26
Female	14	16	10 	40
Total	29	22	15 	66


If one student is chosen at random,

Find the probability that the student was NOT a male that got a "A"

---------------

The full population is 66 persons  (! They just calculated it for you in their table - many thanks !)


The favorable set to choose from is the entire population except those 15 male that got A.


Hence, the probability under the question is   =  = =  = 0.7727 = 77.27%.
