A Ferrari comes with seven options. You may buy the car with any combination of these including none. How many different choices do you have?

To determine the number of different choices when you have seven options for a Ferrari, you can think of each option as a binary choice: you can either include it or not. This gives you (2) options (yes or no) for each of the (7) options. Therefore, the total number of combinations is (2^7), which equals (128). This includes the choice of selecting none of the options as well.
