Expert Solution
Step 1
For two events, A and B, The general formula for probability is as:
P(A or B)=P(A)+P(B)-P(AB).
If two events are mutually exclusive then . Hence, the equation reduces to:
P(A or B)=P(A)+P(B)
We have,
P(A)=0.2
P(B)=0.6
The calculations for P(A or B) is as follows;
P(A or B)=P(A)+P(B)
=0.2+0.6
=0.8
Hence, P(A or B)=0.8
