Suppose the container in Example 3 has 4 nonworking engines. Find the probability that the container will not be shipped.
EXAMPLE 3 Diesel Engines
Wien shipping diesel engines abroad, it is common to pack 12 engines in one container. Suppose that a company has received complaints from its customers that many of the engines arrive in nonworking condition. To help solve this problem, the company decides to make a spot check of containers after loading. The company will test 3 engines from a container at random: if any of the 3 are nonworking, the container will rot be shipped until each engine in it is checked. Suppose a given Container has 2 nonworking engines. Find the probability that the container will not be shipped.
