## FAQs on 08 - Finite and Infinite Sets Video Lecture - Sets and Functions - JEE

 1. What is the difference between finite and infinite sets?
Ans. A finite set is a set that contains a specific number of elements and can be counted, while an infinite set is a set that contains an endless number of elements and cannot be counted.
 2. How can we determine if a set is finite or infinite?
Ans. To determine if a set is finite or infinite, we can count the number of elements in the set. If we can count a specific number of elements, the set is finite. However, if the set has an endless number of elements, it is infinite.
 3. Can a set be both finite and infinite?
Ans. No, a set cannot be both finite and infinite at the same time. A set is either finite or infinite, based on the number of elements it contains. It cannot have a specific number of elements and an endless number of elements simultaneously.
 4. Are natural numbers a finite or infinite set?
Ans. Natural numbers are an infinite set. The set of natural numbers starts from 1 and continues indefinitely, without an end. Therefore, it is classified as an infinite set.
 5. Are real numbers a finite or infinite set?
Ans. Real numbers are an infinite set. The set of real numbers includes all rational and irrational numbers, such as fractions, decimals, and square roots. Since there is an endless number of possible real numbers, the set is considered infinite.
