A coin is tossed and a standard number cube is rolled. What is the probability that the coin shows head and the number cube shows an even number?

A: 1/6

B: 1

C: 1/4

D: 1/2

The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head - - - > (1,2,3,4,5,6) & tail - - - > (1,2,3,4,5,6) }. so the probability is 3/12 = 1/4.

C: 1/4
