Short Answer

TABLE 17-5
$$\text { The following payoff table showsprofits associated witha set of } 2 \text { alternatives under } 3 \text { possible events. }$$ $\quad$ $\quad$ $\quad$ $\quad$ $\text {Action }$
$\begin{array} { c c c } \text { Event } & A & B \\1 & 1000 & 1200 \\2 &500 & 700\\3&300&-200\end{array}$
Suppose that the probability of Event 1 is 0.2, Event 2 is 0.5, and Event 3 is 0.3.
