Refer to Example 4.27 on pages 208-209. Suppose that the developer discontinues the Shalimar model but provides an additional elevation choice, D, for each of the remaining three model choices.
a. Draw a tree diagram similar to the one shown in Fig. 4.28 depicting the possible choices for the selection of a home, including both model and elevation.
b. Use the tree diagram in part (a) to determine the total number of choices for the selection of a home, including both model and elevation.
c. Use the BCR to determine the total number of choices for the selection of a home, including both model and elevation.
