Possible outcomes for three investment alternatives and their probabilities of occurrence are given next.

	Alternative 1							Alternative 2							Alternative 3
	Outcomes			Probability				Outcomes			Probability				Outcomes			Probability
Failure		80			0.20				80			0.30				90			0.30
Acceptable		70			0.40				195			0.20				330			0.50
Successful		165			0.40				230			0.50				425			0.20

Using the coefficient of variation, rank the three alternatives in terms of risk from lowest to highest. (Do not round intermediate calculations. Round your answers to 3 decimal places.)
