A standard 6-sided die has the numbers 1, 2, 3, 4, 5, and 6 on its faces. The even numbers in this range are 2, 4, and 6.
There are a total of 6 possible outcomes when rolling the die, and there are 3 outcomes that are even.
To find the probability of rolling an even number, you can use the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]
So in this case:
\[ \text{Probability of rolling an even number} = \frac{3}{6} = \frac{1}{2} \]
Therefore, the probability of rolling an even number is \( \frac{1}{2} \) or 50%.
