Answer 1

The Venn Diagram showing the above relationships is attached accordingly.

Popularized by John Venn in the 1880s, a Venn diagram is a commonly used diagram type that illustrates the logical relationship between sets. In addition to illustrating basic set connections in probability, logic, statistics, linguistics, and computer science, the diagrams are used in the teaching of elementary set theory.

A Venn diagram shows the logical links between two or more groups of items by using overlapping circles or other shapes. They frequently help to visually arrange things, emphasizing the similarities and differences between the objects.
