For two independent events A and B, the probability that both A & B occur is 1/8 and the probability that neither of them occur is 3/8. The probability of occurrence of A may be

Ea n dF are two independent events. The probability that both Ea n dF happen is 1/12 and the probability that neither Ea n dF happens is 1/2. Then,

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

Probabilities that a plant will live is 3/4 and the probability that another plant lives is 1/3 . The probability that only one of them lives is :

Write the formula for calculating the probability of occurance of an event.

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

The probability of two events A and B are 0.25 and 0.40 respectively. The probability that both A and B . occur is 0.15. The probability that neither A nor B occurs is

If the probability of occurance of an event is 0.6, then find the probability of its non-occurance.

When a die is thrown, find the probability that either an odd number or a multiple of 4 occurs.
