Addition Law

A probability law used to compute the probability of the union of two events. It is P(A ∙ B) = P(A) + P(B) − P(A ∩ B). For mutually exclusive events, P(A ∩ B) = 0; in this case the addition law reduces to P(A ∙ B) = P(A) + P(B).

Probability

The evaluation of how likely it is for an event to happen.

Independent Events

Two or more events where the occurrence of one does not affect the probability of the others occurring.
