Determine whether the number could be the probability of an event. Explain your reasoning -0.25
To determine whether a number can be a probability of an event, we need to consider some key criteria.
Firstly, the probability of an event must always be a non-negative number. Since -0.25 is negative, it cannot represent a probability.
Additionally, probabilities range from 0 to 1, inclusive. A probability of 0 indicates that an event is impossible, while a probability of 1 indicates certainty or that the event will definitely occur. Since -0.25 falls outside this range, it cannot be a probability.
Therefore, based on these criteria, -0.25 cannot be the probability of an event.
