1. An experiment includes selecting a card at random from a 52-card deck. Refer to this experiment and find the probability of the event. (Enter your answer as a fraction.)
A black face card is drawn.
2. A survey was conducted by the local chapter of an environmental club regarding the ownership of alternative fuel vehicles (AFVs) among the members of the group. An AFV is a vehicle that runs on fuel other than petroleum fuels (petrol and diesel). It was found that of the 80 members of the club surveyed, 32 of them own at least one hybrid car, 12 of them own at least one electric car, and 4 of them own at least one hybrid and at least one electric car. (Enter your answers to three decimal places.)
(a) If a member of the club is surveyed, what is the probability that he or she owns only hybrid cars?
(b) If a member of the club is surveyed, what is the probability that he or she owns no alternative fuel vehicles?
