<h3>What is a listing method?</h3>
In Mathematics, a listing method can be defined as a technique which is used to list all the elements or members of a data set, while separating each of them with a comma and enclosing the data set within curly braces.
From the information provided above, we have the following points:
- Polo shirts come with color yellow, red, and green.
- The pants come with color black, blue, and white.
By using the listing method, a list of all the elements in this data set is given by:
List = {(yellow, black), (yellow, blue), (yellow, white), (red, black), (red, blue), (red, white), (green, black), (green, blue), (green, white)}
Number of possible uniforms = 9 uniforms.
