If A and B are two events such that P(A) ≠ 0 and P(B|A) = 1, then

If P(A|B) > P(A), then which of the following is correct : (a) P(B|A) < P(B) (b) P(A ∩ B) < P(A) . P(B) (c) P(B|A) > P(B) (d) P(B|A) = P(B)

If A and B are any two events such that P(A) + P(B) – P(A and B) = P(A), then (a) P(B|A) = 1 (b) P(A|B) = 1 (c) P(B|A) = 0 (d) P(B|A) = 0

If A and B are two events such that A ⊂ B and P(B) ≠ 0, then which of the following is correct? (a) P(A|B) = P(B)/P(A) (b) P(A|B) < P(A) (c) P(A|B) ≥ P(A) (d) P(A|B) ≥ P(A)

If P(A) = 1/2, P(B) = 0, then P(A|B) is (a) 0 (b) 1/2 (c) not defined (d) 1

If A and B are events such that P(A|B) = P(B|A), then (a) A ⊂ B but A ≠ B (b) A = B (c) A ∩ B = Φ (d) P(A) = P(B)

If P(A) = 0.4, P(B) = 0.8 and P(B|A) = 0.6, then P(A ∪ B) is equal to (a) 0.24 (b) 0.3 (c) 0.48 (d) 0.96
