NCERT Solutions for Class 11 Maths Chapter 7: Points to Remember

We have mentioned some of the important points to be remembered from the Class 11 Maths Permutations and Combinations chapter for the students to have a quick revision during the final exams.

  • Fundamental Principles of Counting: Multiplication Principle: Suppose an operation A can be performed in m ways and associated with each way of performing A, another operation B can be performed in n ways, then a total number of performances of two operations in the given order is mxn ways. This can be extended to any finite number of operations.
  • Addition Principle: If an operation A can be performed in m ways and another operation S, which is independent of A, can be performed in n ways, then A and B can be performed in (m + n) ways. This can be extended to any finite number of exclusive events.
  • Factorial: The continued product of the first n natural number is called factorial ‘n’. It is denoted by n! or n! = n(n – 1)(n – 2)… 3 × 2 × 1 and 0! = 1! = 1
  • Permutation: Each of the different arrangements which can be made by taking some or all of a number of objects is called a permutation.
  • Combinations: Each of the different selections made by taking some or all of a number of objects irrespective of their arrangements is called combinations. The number of selection of r objects from; the given n objects is denoted by nCr, and is given by nCr = 𝑛!/r!(𝑛𝑟)!
