Two dice are rolled. Then, the probability that the total score is a prime number is

Options

  1. A1 16
  2. B5 12
  3. C1 2
  4. D7 9

Correct answer

B. 5 12

Step-by-step solution

Let two dice are rolled, the total number of outcomes is 36 . The outcomes when we get a total score as prime number are (1,1),(1,2),(2,1),(1,4),(2,3) , (3,2),(4,1),(1,6),(2,5),(5,2),(3,4),(4,3) , (6,1),(5,6),(6,5)P( total score is a prime number )= 15 36 = 5 12
