Industrial quality control programs often include inspection of incoming materials from suppliers. If parts are purchased in large lots, a typical plan might be to select 20
parts at random from a lot and inspect them. A lot might be judged acceptable if one or fewer defective parts are found among those inspected. Otherwise, the lot is rejected
and returned to the supplier. Find the probability of accepting lots that have the given percentage of defective parts. (Round your answers to three decimal places.)
(Hint: Identify success with a defective part.)
