an empty set
The set of all odd natural numbers less than 10 is [1,3,5,7,9].
The set of natural numbers less than 3 includes the numbers 1 and 2. Natural numbers are positive integers starting from 1, so any number less than 3 within this set would be 1 or 2. This set does not include the number 3 itself since natural numbers start from 1 and do not include 0 or negative numbers.
The empty set is a finite set.
The natural numbers are the counting numbers Thus the set m of those counting numbers less than 5 is: m = {1, 2, 3, 4}
