Q. 14

If <img wid A. (0, 1)

B. (-1/4, 1/3)

C. (0, 1/3)

D. (0, ∞)

Answer :

As 3 events are mutually exclusive and exhaustive.


P(A B C) = P(A) + P(B) + P(C) = 1




5 + 3p = 6


p = 1/3


As 1/3 lies in both intervals given in option (a) and (d)


But a larger value like 100 which comes if we choose option d can make P(A) < 0 which is not possible.


Option (a) is the most suitable choice here.
