List of all possible outcomes of a chance process.

Front

The probability that an event does not occur is 1 minus the probability that the event does occur. In symbols, P(AC) = 1 - P(A).

The complement of event A, written as AC, is the event that A does not occur.

complement

CCSS.HSS.CP.A.1

Front

Two events A and B that have no outcomes in common and so can never occur together. That is, P(A and B) = 0.
