As we have already learned in the introduction, a set is a well-defined collection of objects or people. Sets can be related to many real-life examples, such as the number of rivers in Pakistan
Types of Sets
The sets are further categorized into different types, based on elements or types of elements. These different types of sets in basic set theory are:
Finite set: The number of elements is finite
Infinite set: The number of elements is infinite
Empty set: It has no elements
Singleton set: It has one only element
Equal set: Two sets are equal if they have the same elements
Equivalent set: Two sets are equivalent if they have the same number of elements
Power set: A set of every possible subset.
Universal set: Any set that contains all the sets under consideration.
Subset: When all the elements of set A belong to set B, then A is a subset of B
