        A	B	C     Total
Male	12	3	20	35
Female	7	18	14	39
Total	19	21	34	74


If one student is chosen at random,

Find the probability that the student did NOT get an "C"
------------

Solution 

    P =  (total - (male with C + female with C))/(total male + total female) = %2874+-+34%29%2F74 = 40%2F74 = 20%2F37 = 0.5405  (rounded).    ANSWER
