If A and B are two independent events, then the probability of occurrence of at least one of A and B is given by 1- P(A') P(B').

If A and B are two adjacent events, then prove that the probability of occurance of atleast one of A and B is given by 1-P(A') P(B')

If A and B are any two events, then the probability that exactly one of them occur is

If events A and B are independent, then P(A cap B) =

If A and B are independent events such that P(A) gt 0, P(B) gt 0 , then

If A and B are independent events, P(A)3/5 and P(B)=1/5 then find P(AnnB) .

Let A, B, C be three events. If the probability of occurring exactly one event out of A and B is 1 - a, out of B and C is 1 - 2a, out of C and A is 1 - a and that of occuring three events simultaneously is a^(2) , then prove that probability that at least one out of A, B, C will occur is greater than 1/2.

If A and B are two independent events such that P(overline(A) cap B)=2//15 " and " P(A cap overline(B))=1//6 , then P(B), is

Let E and F be two independent events. The probability that exactly one of them occurs is 11/25 and the probability if none of them occurring is 2/25 . If P(T) denotes the probability of occurrence of the event T , then

If A and B are independent events such that P(B) = 2/7, P(A cup bar B) = 0.8, then P(A) =

A and B are two events such that P(A)!=0, P(B//A) is
