Explanation A set is a well-defined collection of objects; living or non-living. The individual objects in the collection are the members of a set. Sets are also described by listing all their individual members within a pair of braces {} Therefore, a well-defined collection of objects written altogether in the braces {} represents a set. Consider the following example: The set “Names of boys” is wri...
