A dentist studied the number of cavities filled in all of his patients over the last three years. Let X be the number ofcavities filled in the last three years for a randomly chosen patient. The dentist found that the randomvariable, X, had the probability distribution shown in the table.Number ofCavitiesProbability00.3500.15O 1.491.732.9820.30 0.1530.1540.05Let D be the difference in the number of cavities filled in two randomly selected patients. Assuming that cavities arefilled independently of one another, what is the standard deviation of D?
