Calculating Probability

Probability Scale A probability of 0, or 0%, means the event has no chance of happening. A probability of 1/2, or 50%, means the event is just as likely to happen as not to happen. A probability of 1, or 100%, means the event is certain to happen. Can you think of some examples of these different probabilities happening?
