Explanation / Answer

9.a The first step has 4 outcomes, the second has 3, third has 2 and the fourth has 2 possible outcomes.

=> Total number of possible outcomes for the four steps

= 4*3*2*2

= 48.

b. One can only choose one dealership at a time.

The first has 4 outcomes, the second has 3 and the third and the fourth have 2 each.

Total number of outcomes

= 4 + 3 + 2 + 2

= 11.
