Calculate the expected value and that standard deviation of variables X, and Y, given the probability distribution presented in Table 1 (see next page).

Which loss outcome looks less risky? Please explain.

\begin{tabular}{|c|l|l|l|} \hline \multicolumn{2}{|c|}{ProbabilitydistributionofVariableX(lossoutcome)} & ProbabilitydistributionofVariableY(lossoutcome) \\ \hline X(Lossoutcome) & Probability & Y(Lossoutcome) & Probability \\ \hline 1000 & 1/3 & 1000 & 0 \\ \hline 5000 & 1/3 & 5000 & 1 \\ \hline 10000 & 1/3 & 10000 & 0 \\ \hline \end{tabular}
