The probability of simultaneous occurrence of at least one of two events A and B is p. If the probability that exactly one of A, B occurs is q then prove that `P(barA)+P(barB) = 2 - 2p + q`

The probability of simultaneous occurrence of at least one of two events A and B is p.If the probability that exactly one of A,B occurs is q then prove that P(bar(A))+P(bar(B))=2-2p+q

The probability of simultaneous occurrence of at least one of two events A and B is p. If p is the probability that exactly one A, B occurs is q, then prove that : P(A')+P(B')=2-2p+q

If the probability of simultaneous occurrence of two events A and B is p and the probability that exactly one of A, Boccurs is q, then which of the following is'are correct? 1. P(bar(A)) +P(bar(B)) = 2 - 2p - q . 2. P(bar(A) nn bar(B)) = 1- p - q elect the correct answer using the code given below:

The probability of the simultaneous occurrence of two events A and B is p. If the probability that exactly one of A, B occurs is q, then which of the following alternatives is incorrect ?

The probability of the simultaneous occurrence of two events A and B is p. If the probability that exactly one of A, B occurs is q, then which of the following alternatives is incorrect ?

If P(A) and P(B) are the probabilities of occurrence of two events A and B, then the probability that exactly one of the two events occur, is

If the probability that exactly one of the two events A and B occurs is p and the probability that both A and B occur is q, then -
