## FAQs on RD Sharma Class 11 Solutions Chapter 16 - Permutations (Ex 16.2) Exercise 16.2

**1. Is Exercise 16.2 of Chapter 16, Permutations of the RD Sharma Mathematics book difficult?**

Well, if you have understood all the concepts of the permutations from chapter 16 of the RD Sharma Mathematics book in a better manner, and have revised them. Then exercise number 16.2 is not going to be difficult for you. Because all the questions in the said exercise of the RD Sharma Mathematics book are designed to suit the difficulty level of the class 11 students. Hence, you will not find any questions too difficult or too easy to solve, but all are of the same level.

**2. What do Permutations mean?**

In Mathematics, Permutation is an arrangement of the number set in a particular order. It means arranging the sequence of the numbers in all the possible sequences; therefore, the word ‘Permutation’ also means a process of altering the form of the linear order of the given set. Because whenever, they are two or more numbers present in the set, provided that the numbers are different and not the same, there are always two or more than two possibilities for arranging those numbers.

**3. What are the uses of permutations in practical life?**

There are many uses of Permutations in practical life, and it is used in almost all the field of mathematics, as well as in science, especially in the field of technology. In computing technology, permutations are used for sorting the algorithms. It helps in determining the states of particles in quantum physics. In the field of biology, it helps in understanding the RNA sequence of the genes, and not just RNA permutations are used in many other pattern analyses.

**4. Are permutation and Combination the same thing?**

Though in Mathematics Permutation and Combination are, more often than not, used together, there are quite many differences between the two terms. Permutations mean arranging the number set in a particular order, that is to say, it refers to the sequencing of the data, which is known as permuting. While on the other hand combination refers to the selection of the units from the data or the number set, where the order of the selection is not of any importance.
