An aluminum foil manufacturer wants to improve the quality of his product and is trying to develop a probability model for the flaws that occur in a sheet of foil. Assumethat X, the number of haws per square foot, has a Poisson distribution. If faws occur randomly at an average of one flaw per 90 square feet, what is the probability thata box containing a 270 square foot roll will contain more than one flaw? Round your answer to four decimal places, if necessary.

Solution: Let X be the number of flaws per square feet. The average number of flaws per 90 square…
