Answer :
The value of P(A or B) if the probabilities are mutually exclusive is 0.9
Mutually exclusive events
Given the following probability values shown below;
P(A) = 0.60
P(B) = 0.30
If A and B are mutually exclusive, hence;
P(A or B) = P(A)+P(B)
P(A or B) = 0.6 + 0.3
P(A or B) = 0.9
Hence the value of P(A or B) if the probabilities are mutually exclusive is 0.9
