Question

X: x is a positive counting number less 25}

Answer 1

As the givens set A contains 24 elements.

Therefore,

The Cardinality of the set A = 24

Explanation:

Let the given set is A

A = {x: x is a positive counting number less 25}

The set of natural numbers is often termed as the Counting number set.

• As the counting numbers are less than 25.

Thus,

Set A will be:

`A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}`

The Cardinality of the set

The Cardinality of the set represents the total number of elements in a given set.

As the givens set A contains 24 elements.

Therefore,

The Cardinality of the set A = 24
