If A and B are events such that P (A/B) = P(B/A), then

A ⊂ B but A ≠ B A = B A ∩ B = ø P (A) = P (B).

The probability of obtaining an even prime number on each die when a pair of dice is rolled is

0 1/3 1/12 1/36

Two events A and B are said to be independent if:

A and B are mutually exclusive P (A’B’) = [1 – P(A)] [1 – P(B)] P (A) = P (B) P (A) + P (B) = 1.

If A and B are two events such that A ⊂ B and P (B) ≠ 0, then which of the following is correct

P (A / B) = p(B) /p(A) P (A/B) < P (A) P (A/B) ≥ P (A) None of these.

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

A ⊂ B B ⊂ A B = ø A = ø

If A and B are events such that P (A∪B) = 3/4. P(A∩B) = 1/4, P = 2/3 then P(AB) is
