Web26 nov. 2024 · Any Set that is either empty or contains a finite number of elements i.e. countable elements is called a Finite Set. Example S = { x x ∈ N and 50 > x > 30 } is finite since the number of elements that satisfies the condition given are countable. B = {a, e, i, o, u} is finite since it represents the vowel letters in the English Alphabet. Web9 jul. 2024 · For example, the set of vowels in English alphabets, Set A = {a, e, i, o, u} is a finite set as the elements of the set are countable. Infinite set can be understood as a set that is not finite. It is not possible to count the elements of an infinite set.
