Concept

In mathematics, a set is a well-defined collection of  objects or elements. The set is represented by an uppercase symbol, and the number of elements in a finite set is represented by the radix of the set enclosed in  curly braces {…}.

Given

We have given a set A =  {8,10,12,14,16,18,20}  and 4 options which are following

a. 4

b. 8

c. 7

d. 6

Find

We are asked to determine the number of element consisting in set A .

Solution

The number of elements in a set is called the cardinal number, or cardinality, of the set.

This is denoted as n(A), read “n of A” or “the number of

elements in set A.”

The given set A contains 7 elements . It matches with the option (c)

Hence, the option (c) is the correct answer
