Determine which numbers could be used to represent the probability of an event.


The probability of an event is always represented by a number between 0 and 1, inclusive. The possible numbers that can represent the probability of an event follow these rules:

1. **0**: Represents an impossible event (the event will never happen).
2. **1**: Represents a certain event (the event will always happen).
3. **Any number between 0 and 1 (including fractions or decimals)**: Represents an event that has some chance of occurring, but is not certain. For example, 0.5 (or 50%) means the event is equally likely to happen or not happen.

Thus, the numbers that could represent probabilities are:
- **0 ≤ probability ≤ 1**

### Examples:
- 0: Impossible event
- 0.25: 25% chance of occurring
- 0.5: 50% chance of occurring
- 1: Certain event

### Invalid numbers for probabilities:
- Negative numbers (e.g., -0.2)
- Numbers greater than 1 (e.g., 1.5)

**Tip:** Always check if your probability value lies between 0 and 1 when solving real-world problems.
