Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each ool contains 14 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. An nspector chooses 3 parts from among the 14 at random. Two cavities are affected by a temperature malfunction that esults in parts that do not conform to specifications. a) How many samples contain exactly 1 nonconforming part? b) How many samples contain at least 1 nonconforming part?
