Question

State, whether each of the following sets is a finite set or an infinite set:

Answer 1

Step: Check whether the given set is a finite set or an infinite set
We know that,
Finite sets are the sets having a finite/countable number of members.

Infinite sets are the sets having an infinite/uncountable number of members.

Whole number less than 12 are
$11,10,9,8,7,6,5,4,3,2,1$ and $0$

Wo, set of whole number less than $\text{12 = {0,1,2,3,4,5,6,7,8,9,10,11}}$, which are countable

Therefore, given set is infinite.

Hence, the set of whole numbers less than 12 is a finite set.
