Answer:
P(A∪B)=0.8
Explanation:
Given that,
A and B are mutually exclusive events such that,
P(A)=0.5 and P(B)=0.3
We need to find P(A or B). It means we need to find P(A∪B). If two events are mutually exclusive, P(A∩B)=0. So,
P(A∪B)=P(A)+P(B)-P(A∩B)
Putting P(A) and P(B), we get :
P(A∪B)=0.5+0.3-0
P(A∪B)=0.8
So, the value of P(A or B) is 0.8
