If A and B are independent events then write expression for P (exactly one of A, B occurs).

If P(A) = 0.3, P(B) = 0.6, P(B/A) = 0.5, find

If A, B and C are independent events such that P(A) = P(B) = P(C) = p, then find the probability of occurrence of at least two of A, B and C.

If A and B are independent events such that P(A) = p, p(B) = 2p and P (Exactly one of A and B occurs) = 5/9, find the value of p.

Mark the correct alternative in each of the following:

If one ball is drawn at random from each of three boxes containing 3 white and 1 black, 2 white and 2 black, 1 white and 3 black balls, then the probability that 2 white and 1 black balls will be drawn is
