Two dice are tossed. The probability that their product is a prime number is:	Select:	A) 1/12	B) 1/6	C) 1/4	D) 2/9	E) 2/2
Explanation :   Number of possible outcomes = 6x6 = 36.   Favourable outcomes = {1x2,1x3,1x5,2x1,3x1,5x1}   Number of favourable outcomes = 6.   Hence, probability of the event = 6/36 = 1/6.   Answer : 1/6
