i.Based solely on the information in this decision tree, we can predict that A.Tracy will always make the decision to give Amy the choice at Y, and Amy will then choose the lower branch. B.Amy will make a credible promise to pick the lower branch if given the choice at Y and Tracy will make the decision to give Amy the choice at Y. C.Tracy will always make the decision to give Amy the choice at Z and Amy will then choose the upper branch. D.Tracy will always make the decision to give Amy the choice at Z and Amy will then choose the lower branch.

ii.If the payoffs at the end of each branch are as shown, the outcome of this game will be A.Tracy and Amy both get 125. B.Tracy gets 75 and Amy gets 150 C.Tracy gets 300 and Amy gets 200 D.Tracy gets 25 and Amy gets 225
