content area Part 1 After drawing a decision tree, we solve it by working from right to left. When calculating the expected payoff for each event node, A. we add the payoff of each event branch to the event's probability and then multiply these sums. B. we pick the alternative that has the average expected payoff. C. we multiply the payoff of each event branch by the event's probability and then add these products. D. we pick the alternative that has the best expected payoff
