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

$\backslash$table$[[,$Alternative $1,$Alternative $2,$Alternative $3],[,$Outcomes,Probability,Outcomes,Probability,Outcomes,Probability$],[$Failure$,60,0\mathrm{.}40,70,0\mathrm{.}20,70,0\mathrm{.}30],[$Acceptable$,90,0\mathrm{.}20,165,0\mathrm{.}40,220,0\mathrm{.}50],[$Successful$,120,0\mathrm{.}40,250,0\mathrm{.}40,395,0\mathrm{.}20]]$

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