In Example 3d, you might have noticed a new notation, P ( A '). This denotes the complement of an event. In Example 3, the event is making the NHL , so the complement is not making the NHL . The complement can be thought of as a not probability, the chance of an event not happening . If you consider an event and its complement, you know that one or the other must happen. This means that, if you add the probabilities of either happening, you should get 1 or 100%.
