You were analyzing a stock and came up with the following
probability distribution of the stock returns. What is the
coefficient of variation on the company's stock? Round your answer
to two decimal places. For example, if your answer is $345.6671
round as 345.67 and if your answer is .05718 or 5.7182% round as
5.72.
State of the Economy:

Normal - 46.00%
Recession - 34.00%
Stock's Expected Return

I am very lost at solving the standard deviation and would
appreciate a clear breakdown. Thank you for your time!
