Decision tree - basic problem setting Please solve the following decision tree to maximize the expected payoff. $100K 2 2 $120K 60% Down 65% 35% $75K US 40% $55K Down 30% $95K 70% $65K The optimal course of decisions is: at decision node 1, we should choose [Select] at decision node 2, we should choose [Select] The optimal course of decisions is: at decision node 1, we should choose [ Select ] "Up" "Down" Neither at decision node 2, we should choosi The optimal expected payoff of the decision tree is: $ _ ___ K. (Please conduct all calculations with the precision of two decimal places after the dot.) (Please report your result in 000's. For example, if you result is $500K, report "500" in the space provided.)
