What is the probability of rolling an even number on a fair six-sided die?

Probability is about favorable outcomes over total possible outcomes when all outcomes are equally likely. A fair six-sided die has six faces, each with probability 1/6. The even faces are 2, 4, and 6, giving three favorable outcomes. Add their probabilities: 1/6 + 1/6 + 1/6 = 3/6, which simplifies to 1/2. So the chance of rolling an even number is one-half. The other options would require a different count of even faces or total outcomes (two even faces would be 1/3, all rolls even would be 1, and four even faces would be 2/3), but there are exactly three even faces on a six-sided die.
