If A and B are mutually exclusive events, it means they cannot occur at the same time. So the probability of either A or B happening is the sum of their individual probabilities, i.e., P(A or B) = P(A) + P(B) = 0.2 + 0.6 = 0.8. Hence, the correct option is C.

If a and B Are Mutually Exclusive Events with P(A)=
