Step-by-step explanation:
The Venn diagram is a graphic form that represents the elements of a set. To make this representation we use geometric shapes.
To indicate the universe set, we normally use a rectangle and to represent subsets of the universe set we use circles. Within the circles are included the elements of the set.
When two sets have elements in common, the circles are drawn with an intersecting area.
This diagram is constantly used in the commercial area to represent data shared between two different sets of information.
