Shoe manufacturers must know the distribution of foot size of different age groups to decide demand for different sizes. It is found that foot size of men in Ontario is normally distributed with mean 10.8 inches and a standard deviation 1.4 inches. What is the probability that an Ontrio man will have a foot size less than 12 inches?
