The number of distinct computer systems that this person can purchase is equal to twelve (12).
Given the following data:
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:
[tex]_nC_r = \frac{n!}{r!(n-r)!}[/tex]
Where:
Substituting the given parameters into the formula, we have;
³C₁ × ²C₁ × ²C₁ = 3 × 2 × 2
Distinct systems = 12.
