These events are complementary. Let P(A) = probability event will occur. Then the probability it will not occur is: 1 - P(A).

an impossible event has a probability of 0, it will never occur a certain event has a probability of 1, it will always occur

The chance that a given event will occur, usually expressed between the number 0 (will not occur) and 1 (will occur) is called probability.

Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.
