When ordering a certain type of computer, there are 3 choices of hard drive, 4 choices for the amount of memory, 2 choices of video card, and 3 choices of monitor. in how many ways can a computer be ordered?

Since a computer must have one of each element, the possible combinations is simply the product (multiplying) the numbers of each choice:3 x 4 x 2 x 3= 72 ways a comput4er can be ordered
