Answer: P(A) + P(B).
- A P(A) × P(B)
- B P(A) + P(B)
- C P(A) + P(B) - P(A and B)
- D P(A) - P(B)
Correct answer: B. P(A) + P(B)
Explanation: For mutually exclusive events, P(A ∪ B) = P(A) + P(B) (no overlap).
Venn diagram of the universal set U with events A and B, showing the intersection (A and B), the parts unique to each event, and the complement region outside both.
