Question When working backward from the nodes on a binomial tree diagram, the analyst is attempting to calculate:选项：
A.the number of potential outcomes. B.the probability of a given scenario. C.an expected value as of today.解释：
SolutionC is correct. In a tree diagram, a problem is worked backward to formulate an expected value as of today.
A is incorrect because the number of nodes is determined by the number of periods as well as the number of forecasted probabilities per period. These inputs will be used in the model to find the potential outcomes. Working backward will then provide the expected value as of today.
B is incorrect because the probability of a given scenario is estimated by the analyst for use in forecasting ending values.
