Two dice are thrown simultaneously, the probability of obtaining a total score of ( 5 ) is

Options

  1. A( 1 18 )
  2. B( 1 12 )
  3. C( 1 9 )
  4. D( 1 6 )

Correct answer

C. ( 1 9 )

Step-by-step solution

Total number of outcomes is 6 6=36 Sum should be 5, that is, (1,4),(4,1),(2,3),(3,2) Therefore, required probability is P(X)= 4 36 = 1 9
