Question

The probability of happening of an event A is 0.5 and that of Bis 0.3. If A and B are
mutually exclusive events, then find the probability that neither A nor B happen.
​

Answer 1

Step-by-step explanation:

P(Aˉ∩Bˉ)=1−P(A∪B)

Since A and B are mutually exclusive, so  

P(A∪B)=P(A)+P(B)

Hence, required probability =1−(0.5+0.3)=0.2
