Probability of only one of C and B is 1-k
`P(AnnBnnC) =k^2 , kin(0,1)` then Find `P( AuuBuuC)`

Let A,B and C be three events such that the probability that exactly one of A and B occurs is (1-k), the probability that exactly one of B and C occurs is (1 –2k), the probability that exactly one of C and A occurs is (1 –K) and the probability of all A, B and C occur simultaneously is k ^(2), where 0 lt k lt 1. Then the probability that at least one of A, B and C occur is:

The probability of apointment of A at a post is 1/2 and probability of appointment of A at a post is 1/2 and probability of appointment of B is 1/3 . If only one can be appointment, then find its probability.

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that only one of them wins

If A and B are two independent events, then the probability that only one of A and B occur is

A and B are two events such that the probability that both A and B occur is 1/6 and the probability that at 2 least one of them occurs is 2/3 • The probability of the occurrence of A = _____ if P( A) = 2P( B ) .

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that only B wins

The probability of A to fail in an examination is 1/5 and that of B is 3/10 . If the probability that both of them fails is 3/50 , then the probability that only one of A and B fails, is

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that at least one of them wins.

The probability that at least one of A and B occurs is 0.8. If A and B occur simultaneously with probability 0.1, then P(A')+P(B') is

The probability of A winning a race is 1/2, and that for B is 1/3. Find the probability that only A wins
