A refrigerated case holds 24 cans of soft drinks: 6 cola, 6 root beer, 3 orange, 3 sparkling water, and 6 ginger ale. If one can is drawn at random, what is the probability of getting (a) a can of root beer; (b) a can of cola or a can of ginger ale; (c) a can that is neither cola, root beer, nor ginger ale? If 2 cards are drawn from a well-shuffled deck of 52 playing cards, what are the probabilities of getting (a) two spades; (b) two aces; (c) a king and a queen?
