Short Answer

TABLE 17-5
The following payoff table shows profits associated with a set of 2 alternatives under 3 possible events.
$\quad$ $\quad$ $\quad$ $\quad$ $\text {Action }$
$\begin{array} { c c c } \text { Event } & A & B \\1 & 1000 & 1200 \\2 &500 & 700\\3&300&-200\end{array}$

Suppose that the probability of Event 1 is 0.2, Event 2 is 0.5, and Event 3 is 0.3.
-Referring to Table 17-5, what is the standard deviation for Action A?
