Which of the following probabilities could describe an event that is likely but not certain? 0.2 0.5 0.8 1

The probability that could describe an event that is likely but not certain is 0.8. Here's why:

1. Probability is a measure of the likelihood that an event will occur. It is measured between 0 and 1 inclusive. Where 0 indicates that the event will not happen and 1 indicates that the event is certain to happen.

2. In this case, we are looking for a probability that is likely (so it should be closer to 1) but not certain (so it should be less than 1).

3. Out of the given options (0.2, 0.5, 0.8, 1), 0.8 is the highest number that is less than 1. Therefore, 0.8 is the probability that could describe an event that is likely but not certain.
