Two fair dice are rolled. The probability of the sum of digits on their faces to be greater than or equal to 10 is

Options

  1. A1 5
  2. B1 4
  3. C1 8
  4. D1 6

Correct answer

D. 1 6

Step-by-step solution

Total samle points, n(S)=6 6=36 Favourable events =[(6,4),(6,5),(6,6),(5,5),(5,6),(4,6)] Total favourable events, n(E)=6 Required probability = n(E) n(S) = 6 36 = 1 6
