A die is thrown three times,
E : 4 appears on the third toss
F : 6 and 5 appears, respectively on first two tosses.
Find `P(E//F)`

Text Solution

Verified by Experts

The correct Answer is:
Required probability, `P(E//F) = (P(EcapF))/( P(F)) = ((1)/(216))/((1)/(36)) = (1)/(216) xx (36)/(1) = (1)/(6)` .
