Overview of Permutation and Combination Class 11 JEE

Permutation vs. Combination:

  • Permutation: Arranging a set of objects in a specific order. The order of arrangement matters.

  • Formula: nPr = n! / (n - r)! (where n is the total number of objects and r is the number of objects chosen for arrangement)

  • Example: Arranging 3 letters (A, B, C) has 6 possible arrangements (ABC, ACB, BAC, BCA, CAB, CBA).

  • Combination: selecting a set of objects without considering the order. The order of selection doesn’t matter.

  • Formula: nCr = n! / (r! * (n - r)!

  • Example: Choosing 2 players from a team of 11 has 55 possible combinations (AB, AC, AD, …, XY).

Significance for Class 11 and JEE:

  • Foundation for higher mathematics: Mastering these concepts lays the groundwork for various mathematical topics encountered in higher studies.
  • JEE Preparation: Permutation and combination form an essential part of the JEE syllabus, with numerous questions testing your understanding and application skills.
