The expected value of each course of action in a decision tree is determined by starting at the beginning of the tree (the left-hand side) and working toward the end of the tree (the right).

a. True
b. False

False

Explanation:

The expected value of each course of action in a decision tree is not determined by starting at the beginning of the tree, instead it is a process because you need to make a desition and in some extend you espect to have some results but  some of them are uncertain or unespected. in this kind of scheme Squares represent decisions, and circles represent uncertain outcomes. Then you need to calcule the desition nodes giving each option a cost or value, This will give you a value that represents the benefit of each decision. at the end calculating choose the option that has the largest benefit, and take that as the decision made. This is the value of that decision node.
