Step-by-step explanation:

A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.

A set can be made up of elements such as numbers, alphabets, people, cars etc.

For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.

On the other hand, a subset is a part of a larger set.

For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies.
