Which of the following sets are finite or infinite(i) The set of months of a year(ii) (iii) (iv) The set of positive integers greater than 100(v) The set of prime numbers less than 99

Solution: Solution: The set of months of a year - As number of months is always 12, so it will be a final set.
- It is a set of all natural numbers which is infinite.
- It is a set of all natural numbers till 100 as we know the limit. As is a finite set.
The set of positive integers greater than 100 - As positive integers from 100 are infinite and we do not know the limit, it is an infinite set.
The set of prime numbers less than 99 - As prime numbers less than 99 are finite and we know the limit of this set, it is a finite set.
