An unbiased die is rolled. Find the probability of getting:
an even number.

Answer

To find the probability of getting an even number when an unbiased die is rolled, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the total number of outcomes when rolling a die:**
- A standard die has 6 faces, numbered from 1 to 6.
- Therefore, the total number of outcomes is 6.

2. **Identify the favorable outcomes for getting an even number:**
- The even numbers on a die are 2, 4, and 6.
- Thus, the favorable outcomes for getting an even number are: {2, 4, 6}.
- The total number of favorable outcomes (even numbers) is 3.

3. **Calculate the probability:**
- The probability of an event is given by the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
- Substituting the values we found:
\[ \text{Probability of getting an even number} = \frac{3}{6} \]

4. **Simplify the fraction:**
- \(\frac{3}{6}\) simplifies to \(\frac{1}{2}\).

5. **Conclusion:**
- Therefore, the probability of rolling an even number on an unbiased die is \(\frac{1}{2}\).

### Final Answer:
The probability of getting an even number when rolling an unbiased die is \(\frac{1}{2}\).
