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

$\backslash$table$[[,$Alternative $1,$Alternative $2,$Alternative $3],[$Failure$,$Outcomes,Probability,Outcomes,Probability,Outcomes,Probability$],[$Acceptable$,40,0\mathrm{.}20,70,0\mathrm{.}30,80,0\mathrm{.}20],[$Successful$,75,0\mathrm{.}40,180,0\mathrm{.}30,210,0\mathrm{.}60],[,110,0\mathrm{.}40,240,0\mathrm{.}40,420,0\mathrm{.}20]]$

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.
