### Re: Oliver 75 - 13th Question

In a traditionally drawn decision tree, a circle represents ___________.

Yes the correct answer is option D : a decision to which an expected monetary value may be assigned to calculate the most likely pay-off.

A decision tree is one of the tools used to determine quantitative risk analysis used to reach a computed optimal solution using probability distributions as a basis. The circle represents a "chance node," meaning a chance to which an Expected Monetary Value (EMV) may be assigned to calculate the most likely pay-off.

### Re: Oliver 75 - 13th Question

I guess the answer is C. A circle is a chance node.

Some facts on decision trees.

Tree is build left to right but evaluated right to left. This process is known as rolling back the tree.

There two nodes

Chance node: we can calculate the expected payoff represented by the probability distribution at the node.

Decision node: we calculate the largest expected payoff to determine the best action.
