The number of distinct computer systems that this person can purchase is equal to twelve (12).
<u>Given the following data:</u>
- Number of basic units = 3 models.
- Number of keyboard = 2 models.
- Number of printers = 2 models.
In order to determine the number of distinct computer systems that this person can purchase, we would use a mathematical model referred to as combination.
Mathematically, combination is given by this mathematical equation:
<u>Where:</u>
- n is the number of items.
- r is the number of times of choosing items.
Substituting the given parameters into the formula, we have;
³C₁ × ²C₁ × ²C₁ = 3 × 2 × 2
Distinct systems = 12.
