Question

If P(A) = 0.3, P(B) = 0.4, P(C) = 0.8, P(AB) = 0.08,

P(AC) = 0.28, P(ABC) = 0.09, P(A + B + C) ≥ 0.75 and P(BC) = x, then

(A) 0.23 ≤ x ≤ 0.48

(B) 0.32 ≤x ≤ 0.84

(C) 0.25 ≤ x ≤ 0.73

(D) of these

Answer 1

Answer is (D) of these

There will be no x because P(AB) can never be less than P(ABC).
