Required informationGears produced by a grinding process are categorized eitheras conforming (suitable for their intended purpose), degraded(unsuitable for the intended purpose but usable for anotherpurpose), or scrap (not usable). Suppose that 78% of the gearsproduced are conforming, 13% are degraded, and 9% arescrap. Ten gears are selected at random.What is the probability that one or more is scrap?
