Two dice are tossed. The probability that the total score is a prime number is:
Choose the correct answer:
A) 1/6	B) 5/12	C) 1/2	D) 7/9	E) 9/4
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(9/4) =	n(9/4)/n(S)   =	15/36	=	5/12
