(Refer Instruction to students' for the values of a,b,c...). They accepted to sell the building at Muscat first. If it is sold, then based on the market condition either they stop selling further or continue to sell one of the other property. If they are not able sell the property with in a year then they will quit the contract with you. If they sold the second property then they again based on the market condition they may accept to sell the third property or stop selling the third property. The cost of the properties and probabilities of sales are given below. Draw a tree diagram for this decision process and derive a decision which is more beneficial for the Marketing Company. Do all the calculations properly rounded to four decimal places.
