Two dice and are rolled. If it is known that the number on is then the probability that the sum of the numbers on the two dice will be greater than is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Let, X be the event when sum of digits on the two dice is greater than 9 and Y be the event when the number on the dice B is 5. ⇒X∩Y∈5,5, 6,5 Now, PXY=PX∩YPY ⇒PXY=23616 ⇒PXY=13
