A six - faced die has 3 faces red, 2 blue 1 white. The die is rolled. Find the probability that the face that shows is:
red

Answer

To find the probability of rolling a red face on a six-faced die with 3 red faces, 2 blue faces, and 1 white face, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the total number of faces on the die.**
- The die has 3 red faces, 2 blue faces, and 1 white face.
- Therefore, the total number of faces = 3 (red) + 2 (blue) + 1 (white) = 6 faces.

2. **Identify the number of favorable outcomes for rolling a red face.**
- The number of favorable outcomes (red faces) = 3.

3. **Use the probability formula.**
- The formula for probability is given by:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

4. **Substitute the values into the formula.**
- Here, the number of favorable outcomes (red faces) = 3 and the total number of outcomes (total faces) = 6.
- Therefore, the probability of rolling a red face is:
\[ \text{Probability of red face} = \frac{3}{6} \]

5. **Simplify the fraction.**
- \(\frac{3}{6} = \frac{1}{2}\)

6. **State the final answer.**
- The probability of rolling a red face on the die is \(\frac{1}{2}\) or 0.5.
