Two dice are thrown together .What is the probability that the sum of the number on the two faces is divided by 4 or 6.

A) 7/18

B) 14/35

C) 8/18

D) 7/35

Answer: A) 7/18

Explanation:

Clearly, n(S) = 6 x 6 = 36

Let E be the event that the sum of the numbers on the two faces is divided by 4 or 6.

Then,E = {(1,3),(1,5),(2,2),(2,4),(2,6),(3,1),(3,3),(3,5),(4,2),(4,4),(5,1),(5,3),(6,2),(6,6)}

n(E) = 14.

Hence, P(E) = n(E)/n(S) = 14/36 = 7/18
