The cholesterol level of a person, after a blood test, can be classified as normal, acceptable, or high. From the data of previous blood tests in a hospital, it has been estimated that the probability a patient has acceptable cholesterol level is twice as much as the probability of having normal cholesterol level and three times as much as the probability of having high cholesterol level. Find the probability that a randomly selected patient in this hospital belongs to each of these three groups according to their levels of cholesterol in their blood.
