AMutually exclusive
BPerfectly independent
CEqually likely always
DConditionally certain
Answer & Solution
Correct answer: A. Mutually exclusive
1. Some pairs of events share no outcome at all, so one rules the other out.
2. Events like that are called mutually exclusive.
3. Independence is a different idea: it means one event does not change the chance of the other.
