Two dice are thrown simultaneously. If A is event of getting the sum of the numbers on two dice as greater than or equal to 8 and B is the event of getting a number less than or equal to 3 on atleast one of the die. Then, P(B / A)=

Options

  1. A5 15
  2. B6 15
  3. C7 15
  4. D8 15

Correct answer

B. 6 15

Step-by-step solution

Event aligned & array l A=(2,6),(3,5),(4,4),(5,3),(6,2),(3,6),(4,5),(5,4) (6,3),(4,6),(5,5),(6,4),(5,6),(6,5),(6,6) array & and event A B=(2,6),(3,5),(5,3),(6,2),(3,6),(6,3) & So, P(B / A)= P(B A) P(A) = n(B A) n(A) = 6 15 or 2 5 . aligned
