The image shows a table representing a probability distribution with the following values:

| x | P(x) |
|---|------|
| 0 | 0.3  |
| 1 | 0.25 |
| 2 | 0.3  |
| 3 | 0.15 |

Below the table, there is a question:

"Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places."

There is an empty box provided for the answer.
