**Table of Numbers of Sleepwalkers and Probabilities**

This table displays the probabilities associated with different numbers of sleepwalkers, represented by the variable \( x \).

| \( x \) | \( P(x) \) |
|---------|-----------|
| 0       | 0.187     |
| 1       | 0.363     |
| 2       | 0.291     |
| 3       | 0.132     |
| 4       | 0.026     |
| 5       | 0.001     |

### Description:

- **Variable \( x \):** Represents the number of sleepwalkers.
- **Probability \( P(x) \):** Indicates the likelihood of each corresponding number of sleepwalkers occurring.

### Interpretation:

- **\( x = 0 \):** Probability of no sleepwalkers is 0.187.
- **\( x = 1 \):** Probability of one sleepwalker is 0.363, the highest probability in this dataset.
- **\( x = 2 \):** Probability of two sleepwalkers is 0.291.
- **\( x = 3 \):** Probability of three sleepwalkers is 0.132.
- **\( x = 4 \):** Probability of four sleepwalkers is 0.026.
- **\( x = 5 \):** Probability of five sleepwalkers is 0.001, the lowest probability.

The table neatly organizes potential outcomes and their respective probabilities, offering insight into the likelihood of each scenario.
