Question

You are shopping for a car. You are looking at a model that has 5 different exterior color options, 4 different interior color options, 2 different wheel choices and 3 choices for a sound system. how many different unique cars could be formed?

Answer 1

120

Step-by-step explanation

The car model has the following options:

• 5 exterior colors

,

• 4 interior colors

,

• 2 wheel choices

,

• 3 sound system choices

Each choice is independent of the other - i.e. the interior color does not depend on the exterior color or the wheel choice. So,

`5\cdot4\cdot2\cdot3=120`

Hence, 120 unique cars can be formed.
