The probability of rolling an even number on a standard six-sided die is 1/2 (50%).
Explanation
On a standard number cube (die), the even faces are 2, 4, and 6. There are 3 favorable outcomes out of 6 total possible outcomes, so the probability is P(even) = 3/6 = 1/2 = 50%. This means that, over many rolls, about half of the results will be even. If the die had a different number of faces, the probability would be the number of even faces divided by the total number of faces.
Key Points
- 1, There are three even faces on a standard die: 2, 4, and 6.
- 2, The total number of possible outcomes is 6, so the probability is 3/6.
- 3, This simplifies to 1/2, which is 50%.
