Question

Define and give two examples
finite set ​

Answer 1

Answer:

finite set is a set that has a finite number of elements. Informally, a finite set is a set which one could in principle count and finish counting. For example, is a finite set with five elements. The number of elements of a finite set is a natural number and is called the cardinality of the set.

Examples of finite set:

Let P = {5, 10, 15, 20, 25, 30} Then, P is a finite set and n(P) = 6.

Let Q = {natural numbers less than 25} ...

Let R = {whole numbers between 5 and 45} ...

Let S = {x : x ∈ Z and x^2 – 81 = 0} ...

The set of all persons in America is a finite set.

Answer 2

Answer:

Definition and terminology

In combinatorics, a finite set with n elements is sometimes called an n-set and a subset with k elements is called a k-subset. For example, the set {5,6,7} is a 3-set – a finite set with three elements – and {6,7} is a 2-subset of it.
