alleryFor mutually exclusive events A and B, P(A or B) equals:
AP(A) × P(B)
BP(A) + P(B) (since they cannot both occur)
CP(A) + P(B) - P(A and B)
DP(A) - P(B)
Answer & Solution
Correct answer: B. P(A) + P(B) (since they cannot both occur)
Mutually exclusive: A and B cannot occur together, so P(A and B) = 0. Then P(A or B) = P(A) + P(B).
