Complementary event

（重定向自Complementary events）

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive. Generally, there is only one event B such that A and B are both mutually exclusive and exhaustive; that event is the complement of A. The complement of an event A is usually denoted as A′, A or A. Given an event, the event and its complementary event define a Bernoulli trial: did the event occur or not?
