Question

The probability of the event A occuring is  0.5 and of B occuring is 0.3.If A and B are mutually exclusive events then the probability of neither A nor B occuring is
 


Solution

A and B are mutually exclusive events.
∴P(A∩B)=ϕ=0

P(A∪B)=P(A)+P(B)−P(A∩B)
            ⇒0.5+0.3 - 0
            ⇒0.8
P(A∪B)′ = 1−P(A∪B)
              ⇒1−0.8
              ⇒0.2
