Question

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

Answer 1

P(A) = 0.5 

Since A and B are mutually inclusive events

P(B) = 0.3 events.

P(\(\bar{A}\))∪P(\(\bar{B}\)) = 1 – [P(A) + P(B)]

= 1 – [0.5 + 0.3] = 0.2
