Given a set A, the complement of A, denoted A or A' , is the set of elements that are not members of A

The probability of an event A, given that another event, B, has

Two or more events in which the outcome of one event affects the outcome of another

A member or item in a set

Events whose outcomes do not influence each other.

The set of all elements contained in all of the given sets, denoted

Two events that cannot occur simultaneously, meaning that the probability of the intersection of the two events is zero; also known as disjoint events

Events that can occur simultaneously - they have an intersection

The set of all possible outcomes from an experiment.

a set in which every element is also contained in a larger set.

The set of all elements that belong to at least one of the given two or more sets denoted ∪.
