If a fair die is rolled, probability of getting an even number is what?

• A. 1/3
• B. 1/2
• C. 2/3
• D. 1/4

Answer: (B)

When rolling a fair die, each face is equally likely, so the probability is the number of favorable outcomes divided by the total number of outcomes. There are three even faces (2, 4, 6) out of six possible faces, so the probability is 3/6, which simplifies to 1/2. This matches the idea that half of the possible results are even. The other options don’t fit because they would require a different count of favorable outcomes: two evens would give 1/3, four evens would give 2/3, and one even would align with 1/6 or 1/4 only in different setups, not with six equally likely outcomes.
