A person's blood glucose level and diabetes are closely related.  Let x be a random variable measured in milligrams of glucose per deciliter of blood.  After a 12-hour fast, the random variable x will have a distribution that is approximately normal with μ = 85 and σ = 25.  After 50 years of age, both the mean and standard deviation tend to increase.  What is the probability that, for an adult under 50 years old, after a 12-hour fast, x is more than 60?
