Question

a card is drawn from a standard deck of cards. determine whether the events are mutually exclusive or inclusive. then, find the probability: P(a 4 or a club)

Answer 1

is there a 4 of clubs? if so then not mutually exclusive

Answer 2

13 clubs and 4 "fours" but you don't count the 4 of clubs twice, so answer is 16/52

P(4 or club) = P(4) + P(club) - P(4andClub)
