Simple Decision Tree Part

(a) Suppose that you need to construct a simple decision tree that shows the logical sequence of the decision problem. Select the correct sketch of the decision tree based on the information above.

Note that P(S)=probability of strong demand, P(W)=probability of weak demand. Also, we use the following notations:

P₁=Payoff 1 , P₂=Payoff 2 , P₃=Payoff 3 , P₄=Payoff 4 , P₅=Payoff 5 , P₆=Payoff 6 .
