Expected Return and Risk $($SD$)$ estimation. Based on the data below, estimate the following:

a$.$ The expected return and risk $($SD$)$ of Asset A$.$ As seen in the table below, there are two possible states of the economy $($S$),$ each with a given probability of happening $($Pr$),$ and the return $(R)$ that we expect to obtain from Asset $A$ in each of the possible states of the economy.
