a. Develop a decision tree for this problem. Draw this tree by hand and include it along with your submission. . Do not put any numbers (probabilities, costs, etc.) on your drawing. . The tree should show the structure and logic of the decision process. . Distinguishing between decision and chance nodes, and naming the various nodes and branches, is critical. . Create a tree that is as general as possible - do not eliminate certain branches from consideration because of the specific values of the inputs as presented in the case. . Recall that the key to success is determining what decision/event happens first, and then building out the tree in sequential order. b. Implement your Decision Tree in Precision Tree. Then print out your solved decision tree on a single page and attach it as a part of your submission. c. What is the optimal decision according to the EMV criterion
