Two dice are rolled simultaneously. The probability that the sum of the two numbers on the dice is a prime number, is

Options

  1. A5 12
  2. B7 12
  3. C9 14
  4. DNone of these

Correct answer

A. 5 12

Step-by-step solution

Given that, A= 2,3,5,7,11 Required Probability aligned &=P(X=2)+P(X=3)+P(X=5) &+P(X=7)+P(X=1 &= 1 36 + 2 36 + 4 36 + 6 36 + 2 36 = 15 36 = 5 12 aligned
