Determine whether each number could be the probability of an event. Explain your reasoning.

To determine whether each number could be the probability of an event, we need to consider the properties and constraints of probability.
1. Probability values range from 0 to 1. Any number outside this range cannot be a probability.
2. A probability of 0 means the event is impossible, while a probability of 1 means the event is certain to occur.
Let's apply these considerations to each number:
1.5:
This number is greater than 1, which is outside the valid range for probabilities. Therefore, 1.5 cannot be the probability of an event.
1:
This number is within the valid range of probabilities. A probability of 1 means the event is certain to occur. So, 1 could be the probability of an event, indicating that the event is certain to happen.
