The events are not mutually exclusive because D. The sum of P(A) and P(B) is not equal to P(A or B).
Given that
- probability for event A, P(A) = 0.3.
- probability for event B, P(B) = 0.6.
- the probability of events A or B, P(A or B) = 0.8.
For mutually exclusive events, P(A) + P(B) = P(A or B).
So, P(A) + P(B) = 0.3 + 0.6 = 0.9
P(A or B) = 0.8
Since P(A) + P(B) = 0.9 ≠ P(A or B) = 0.8
The events are not mutually exclusive.
So, the events are not mutually exclusive because D. The sum of P(A) and P(B) is not equal to P(A or B).
