They are not difficult, and are of a basic type in this topic. Follow some of the examples in your text or in your class notes.
e.g. for the above:
For each of the 3 body styles, you can choose 2 engines, so far you have
3*2 or 6 ways.
For each of those 6 ways, you can choose 7 different colours, so how about
3*2*7 or 42 different ways to select a car.
