Final answer:
Pairs A and C are not mutually exclusive, while Pair B is mutually exclusive.
Step-by-step explanation:
In order to determine if the pairs of events are mutually exclusive, we need to consider if the events share any common outcomes. If the events share at least one outcome, they are not mutually exclusive. Let's consider each pair:
Pair A: Rolling an even number and Rolling a prime number. These two events are not mutually exclusive because the number 2 is both even and prime.
Pair B: Rolling an even number and Rolling an odd number. These two events are mutually exclusive because no number can be both even and odd.
Pair C: Rolling an even number and Rolling a number smaller than 3. These two events are not mutually exclusive because the number 2 is both even and smaller than 3.
