Question

A person buying a personal computer system is offered a choice of three models of the basic unit, two models of keyboard, and two models of printer. how many distinct systems can be purchased?

Answer 1

The number of distinct computer systems that this person can purchase is equal to twelve (12).

Given the following data:

• Number of basic units = 3 models.

• Number of keyboard = 2 models.

• Number of printers = 2 models.

How to calculate the number of distinct systems.

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:

$_nC_r = \frac{n!}{r!(n-r)!}$

Where:

• 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.
