Suppose an individual plays a gambling game where it is possible to lose $1.00, break even, win $3.00, or win $10.00 each time she plays. The probability distribution for each outcome is provided by the following table:
Outcome | Probability
-1.00 | 0.30
0.00 | 0.35
3.00 | 0.25
5.00 | 0.10
Find the mean and standard deviation.
