Alternative Fuel Vehicles 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) or that does not involve solely petroleum fuels. It was found that of the 80 members of the club surveyed, 22 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. If a member of the club selected at random is surveyed, what is the probability that he or she: a. Owns only hybrid cars? b. Owns no alternative fuel vehicles?
