A standard deck of cards contains 52 cards. One card is selected from the deck. (a) Compute the probability of randomly selecting a jack or ace. ​(b) Compute the probability of randomly selecting a jack or ace or nine. ​(c) Compute the probability of randomly selecting a king or diamond.

Solutions

Expert Solution

Total cards = 52

a) P(jack or ace) = P(jack) + P(ace) - P(jack and ace)

                           = 4/52 + 4/52 - 0

                           = 2/13

b) P(jack or ace or nine) = P(jack) + P(ace) + P(nine)

                                       = 4/52 + 4/52 + 4/52

                                       = 3/13

c) P(king or diamond) = P(king) + P(diamond) - P(king and diamond)

                                   = 4/52 + 13/52 - 1/52

                                   = 16/52

                                   = 4/13
