Asked by a

The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8.

Why are the events not mutually exclusive?

The sum of P(A) and P(B) is less than P(A or B).
The product of P(A) and P(B) is less than P(A or B).
The product of P(A) and P(B) is not equal to P(A or B).
The sum of P(A) and P(B) is not equal to P(A or B).

"The sum of P(A) and P(B) is not equal to P(A or B)."

Explanation: For mutually exclusive events P(A ∪ B) = P(A) + P(B). Here 0.3 + 0.6 = 0.9 ≠ 0.8. In fact P(A ∩ B) = 0.3 + 0.6 − 0.8 = 0.1 > 0, so they overlap.
