An automobile manufacturer has problems with sticking accelerator pedals. they have come up with what they believe is a solution to the problem, but to test it exhaustively, they must try it in one sample of all possible configurations of their non-hybrid models. there are ten models, each available in three engine sizes, with two transmission types (manual and automatic) and two drive sides (lefthand drive and right-hand drive). if the company must test one vehicle of each possible configuration, how many vehicles do you test?
