You're on a roll — Step 1: Definition of a Set. A set is a well-defined collection of distinct objects. These objects are called elements or members of the set. Sets are usually denoted by capital letters, and their elements are enclosed in curly braces \\. Step 2: Types of Sets with examples. • Empty Set (Null Set): A set containing no elements. It is denoted by or \\. Example: The set of all even prime numbers greater than 2. This set is because 2 is the only even prime number. • Singleton Set: A set containing exactly one element. Example: The set of all even prime numbers. This set is \2\. • Finite Set: A set with a countable number of elements. The process of counting the elements must come to an end. Example: The set of days in a week. This set is \Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday\. • Infinite Set: A set with an uncountable number of elements. The process of counting the elements would never end. Example: The set of all natural numbers. This set is \1, 2, 3, \. • Equal Sets: Two sets A and B are said to be equal if they contain exactly the same elements. Example: If A = \1, 2, 3\ and B = \3, 1, 2\, then A = B. • Subset: A set A is a subset of set B if all elements of A are also elements of B. It is denoted by A B. Example: If A = \1, 2\ and B = \1, 2, 3\, then A B. • Universal Set: The set of all elements under consideration in a particular context. It is usually denoted by U. Example: If we are discussing numbers, the set of all real numbers R could be a universal set. • Disjoint Sets: Two sets are disjoint if they have no elements in common. Their intersection is an empty set. Example: If A = \1, 2, 3\ and B = \4, 5, 6\, then A and B are disjoint sets. What's next? 📸
