1.

The probability of an event A occurring is 0.5 and B occurring is 0.3. IfA and B are mutually exclusive events, then find the probability of neither A nor B occurring

Answer»

Answer:0.2

Step-by-step EXPLANATION:

A and B are mutually EXCLUSIVE events... P(AΠB)=Φ=0

P(A U B)=P(A)+P(B)-P(AΠB)

=0.5+0.3

=0.8

P(A U B)'=1-P(A U B)

=1-0.8

=0.2
