hello!
First, let's write the possibilities of each thing:
2 body styles (2 or 4 doors)
3 interior (deluxe, luxury, or special edition)
2 drive trains (front-wheel or four-wheel)
Now, let's write the possibility chosen by the exercise:
4 door, special edition, and four-wheel drive model.
we must calculate the probability of each of these choices happening, and then multiply them up:
Now that we know the possibilities of each one of the choices, we have to multiply it.
