Answer: 2160
Step-by-step explanation:
Given : At a computer store, a customer is considering 10 different computers, 6 different monitors, 9 different printers and 4 different scanners.
We assume that each of the components is compatible with one another and that one of each is to be selected.
then by Fundamental counting principle , the number of different computer systems possible is given by :-

Hence, the number of different computer systems possible= 2160
- The Fundamental Counting Principle is a technique in Mathematics to calculate the number of possible outcomes by multiplying the events together .
