How many different models can be made?

Question

The 2013 Sierra 1500 pickup truck by GMC comes with six body styles, two drive types, nine exterior colors, two interior colors, two styles of wheels, three choices of engines, and three choices of automatic transmissions. How many different models of the pickup truck can be built on the basis of these options?

Answer 1

Just apply the fundamental principle of counting.

 

If you go to a restaurant that offers 3 types of salads, 5 main dishes and 4 desserts you have

 

3*5*4=60 different 3-course meals to select from.

 

Try to apply the same idea to your problem...easy.
