Answer:
As the givens set A contains 24 elements.
Therefore,
The Cardinality of the set A = 24
Step-by-step 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:
<u>The Cardinality of the set</u>
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
