AThey cannot both happen
BThey must both happen
CThey happen one after another
DThey have the same chance
Answer & Solution
Correct answer: A. They cannot both happen
1. Mutually exclusive events share no outcomes at all.
2. So there is no outcome that puts both events into play at the same time.
3. Rolling a number that is both even and odd is impossible, so those two events are mutually exclusive.
4. The probability that both occur together is therefore zero.
