At а lоcаl cаr rental lоt there is an emplоyee, Ralph, who returns cars without filling the tank. If the lot has 12 of a specific model of car for rental, and Ralph has returned 5 of them. a.) If we are to randomly select 3 cars what is the probability that At most 1 of the cars requires fuel before it can drive off the lot?           b.) Recalculate the probability above if we know that Ralph only returned 3 cars to the lot.           c.)
