Question

Two dice are tossed. The probability that the total score is a prime number is:
A) 5/12
B) 1/6
C) 1/2
D) 7/9

Answer 1

Here in this case the clear probability is n(s) that comes to 6x6 i.e 36.

Let us take E as the event where the sum of the outcome is a Prime Number.

Hence E is {(6,5), (6,1), (5,6), (5,2), (4,3), (4,1), (3,4), (3,2), (2,5), (2,3), (2,1), (1,6), ((1,4), (1,2), (1,1)} n(E) = 15 So, P(E) is n(E) / n(S) which is 15 / 36 = 5/12

So, option A is the correct answer.
