Two dice are tossed. The probability that the total score is a prime number is:	Choose the correct choice from the following
A) 5/12 B) 5/10 C) 6/12 D) 9/12 E) 4/12
Clearly, n(S) = (6 x 6) = 36.   Let E = Event that the sum is a prime number.   Then E	= { (1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4, 3),   (5, 2), (5, 6), (6, 1), (6, 5) }   n(E) = 15.   P(E) = n(E)/n(S) = 15/36	= 5/12.   5/12nswer:5/12
