Suppose a computer chip manufacturer knows from experience that in an average production run of 5000 circuit boards, 100 will be defective. How many defective circuit boards can be expected in a run of 24,000 circuit boards?
100 defective / 5000 circuit boards * 24,000 circuit boards = 480 defective circuit boards
100 defective / 5000 circuit boards * 24,000 circuit boards = 480 defective circuit boards
