Answer» There are various types of sets: (i) Finite set: A set having no elements or a definite number of elements is called a finite set. Ex. V = The set of vowels of english alphabet = { a, e, i, o, u} (ii) Infinite set: A set having unlimited number of elements is called an infinite set. Ex. N = The set of natural numbers = { 1, 2, 3, 4 , ....} (iii) Empty set: A set containing no element is called the empty or null or void set. The symbol for empty set is φ. φ = { } (iv) Singleton set: A set containing only one element is called a singleton set. Ex. {2}, {a}, {0} Note : { } is the empty set whereas {0} is a singleton set. |
