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 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.
