$(9\mathrm{.}28)$ An assembly line runs and produces a large number of units. At the end of the line an inspector checks the product, labeling it as either conforming or nonconforming. The average fraction of nonconforming is $0\mathrm{.}10.$ When a sample size $10$ is taken, what is the probability that $5$ nonconforming units will occur?
