Question

Find n(A) for the following set. A={a,b,c,...,z}

Answer 1

n(A) = 26

Solution:

Let us first define the cardinal number of the set.

Cardinal number of the set:

The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A).

Given set: A = {a, b, c, .... z}

We know that, there are 26 elements in the alphabet "a to z".

Number of elements in the set A = 26

Hence n(A) = 26.
