If a fair six-sided die is rolled, what is the probability of obtaining an even number?

• A. 1/2
• B. 1/3
• C. 2/3
• D. 3/4

Answer: (A)

On a standard six-sided die, the even faces are 2, 4, and 6—three outcomes. There are six possible faces in total, all equally likely. So the probability of rolling an even number is 3 out of 6, which simplifies to 1/2. The fair die means each face has the same chance, so exactly half of the outcomes are even.
