Sum six is : 15,51,24,42,33 sum 9 is 45,54,36,63, probability that sum is neither 6 nor 9 is = 1 - sum is 6 or 9 p= 1- (5÷36 )(4÷36). P = 27÷36=0.75

Probaility=27/36=0.75

Therefore there are (36 - 9) 27option in which the answer would be neither 6 nor 9

The option are 1 5,2 4,3 3,4 2,5 1,3 6,4 5,5 4,6 3
