Permutation and Combination — Syllabus & Topics
Topics covered in Permutation and Combination for JEE Advanced Mathematics.
Topics in Permutation and Combination
Fundamental Principles of Counting
- Multiplication Rule: If work A can be done in m ways and work B in n ways, then both works together can be done in m × n ways
- Addition Rule: If work A can be done in m ways and work B in n ways (mutually exclusive), then either work can be done in (m + n) ways
- These principles form the foundation for all permutation and combination problems
Factorial Notation
- n! = n × (n-1) × (n-2) × ... × 3 × 2 × 1
- By convention, 0! = 1
- Factorial is used extensively in permutation and combination formulas
Permutations
- Permutation deals with arrangements where order matters
- ⁿPᵣ represents permutations of n objects taken r at a time
- When repetition is allowed: nʳ arrangements possible
Combinations
- Combination deals with selection where order doesn't matter
- ⁿCᵣ represents combinations of n objects taken r at a time
- ⁿCᵣ = ⁿCₙ₋ᵣ (symmetric property)
