Easy -1.8 This is a 1-mark multiple choice question testing direct recall of the definition of mutually exclusive events (P(A ∩ B) = 0). It requires no calculation or problem-solving, just recognition of a basic probability concept typically learned early in the statistics curriculum.
A and B are mutually exclusive events.
Which one of the following statements must be correct?
Tick (\(\checkmark\)) one box.
[1 mark]
\(P(A \cup B) = P(A) \times P(B)\)
\(P(A \cup B) = P(A) - P(B)\)
\(P(A \cap B) = 0\)
\(P(A \cap B) = 1\)
