Two dice are rolled, If both dice have six faces numbered 1,2,3,5,7,11 , then the probability that the sum of the numbers on upper most face is prime is

Options

  1. A1 4
  2. B3 4
  3. C1 9
  4. D2 7

Correct answer

A. 1 4

Step-by-step solution

Two dice are rolled. n ( S )=36 A : Event that the sum of the numbers on upper most face is prime. aligned & A= (1,1),(1,2),(2,1),(2,3),(2,5),(2,11), & (3,2),(5,2),(11,2) aligned P ( A )= 9 36 = 1 4
