Porphyrin is a pigment in blood and other body fluids that is significant in body energy and storage. Let x be a random variable that represents the number of milligrams of porphyrin per deciliter of blood. In healthy adults x is approximately normally distributed with μ = 38 and σ = 12. What is the probability that x is less than 60?
