Question
The image shows a table representing a probability distribution with two columns: 

- **x**: The possible outcomes of a random variable.
- **P(x)**: The probability of each outcome.

The table is as follows:

| **x** | **P(x)** |
|-------|----------|
| 0     | 0.2      |
| 1     | 0.25     |
| 2     | 0.2      |
| 3     | 0.35     |

Below the table, the text reads: "Find the mean of this probability distribution. Round your answer to one decimal place."

There is a blank space provided for the answer. 

To calculate the mean (expected value) of a probability distribution, use the formula:

\[ \text{Mean} = \sum (x \times P(x)) \]

Calculate:

\[ (0 \times 0.2) + (1 \times 0.25) + (2 \times 0.2) + (3 \times 0.35) \] 

Round the final result to one decimal place.
