We have been hired to help an eyeglass company determine how many sets of eyeglasses leave their facility defective. They only assemble the components and only manufacture the lenses. For one set of glasses they require 2 lenses, 2 arms, 2 screws and one frame. Their suppliers have supplied them with the following defective percentages: a frame 1.5 %, an arm
2.0 % and a screw 0.5 %. They know from internal quality control checks that each eye lens has a 0.1% defective percentage. What percentage of the assembled glasses that leaves the factory is defective?
