Answer :

We know that a finite set is the set in which the number of elements of the set are finite and an infinite set is the set in which the number of elements of the set are not finite.


(i) Let ‘M’ be the set of months in a year.


M = {January, February, March, April, May, June, July, August, September, October, November, December}


There are 12 elements in ‘M’.


‘M’ is finite.


(ii) {1, 2, 3 … 99, 100}


There are 100 elements in the above set.


The given set is finite.


(iii) Let ‘P’ be the set of prime numbers less than 99.


P = {2, 3, 5, 7, 11 … 89, 97}


There are 25 elements i.e. prime numbers less than 99.


P is finite.
