Hooper Chemical Company, a major chemical firm that uses such raw materials as carbon and petroleum as part of its production process, is examining a plastics firm to add to its operations. Before the acquisition, the normal expected outcomes for the firm were as follows:

$\backslash$table$[[,$Outcomes $($$ millions$),$Probability$],[$Recession$,$$$30,0\mathrm{.}1],[$Normal economy,$50,0\mathrm{.}3],[$Strong economy,$70,0\mathrm{.}6]]$

Compute the expected value, standard deviation, and coefficient of variation prior to the acquisition.

Note: Do not round intermediate calculations. Enter your dollar answers in millions rounded to $2$ decimal places $($e$.$g$.,$ $$12,300,000$ should be entered as $"12\mathrm{.}30").$ Round the coefficient of variation to $3$ decimal places.
