Define a set and give 3 examples

Answer 1

A set is a well-defined collection of distinct objects, considered as an object in its own right. The objects in a set are called its elements or members. Sets can contain anything: numbers, letters, symbols, or even other sets. Sets are usually denoted by curly braces {}.

Examples of Sets:

1. Set of Natural Numbers Less Than 5: $$A=1,2,3,4$$

2. Set of Vowels in the English Alphabet: $$B=a,e,i,o,u$$

3. Set of Primary Colors: $$C=red,blue,yellow$$

These examples illustrate how sets can consist of numbers, letters, or items from a specific category.
