Deck
A pack of cards used in games, consisting typically of 52 pieces divided into four suits.
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).
