A construction company has two divisions: ceilings and floors. The amount of revenue for the ceiling division, C, is approximate
ly Normally distributed with a mean of $2.6 million per year and a standard deviation of $0.9 million per year. The amount of revenue for the flooring division, F, is approximately Normally distributed with a mean of $3.1 million per year and a standard deviation of $1.1 million per year.
