"Decision Tree"

Use the same example of bill's finding a summer job$($see the material at your hand$)$ with modified values as below, compute the Expected Monetary Value$($EMV$)$ of decision and event nodes $($A$$B$$C$$D$$E$)$ and describe the optimal decision strategy in this case. Finally, by doing sensitivity analysis of $P,$ compute the critical value $P**?$

a$)$ Compute the EMV of different nodes.

EMV$(A)=$

EMV$(B)=$

EMV$(C)=$

EMV$(D)=$

EMV$(E)=$

b$)$ By doing sensitivity analysis of $P,$ compute the critical value $P^{**}($the dividing point Bill would change his original optimal strategy$).$
