Formula Sheet — Permutations And Combinations

Important formulas and equations from Permutations And Combinations for TG EAPCET Mathematics.

Formulas — Permutations And Combinations

Fundamental Counting Principles

Total ways = m × n
Total ways = m + n

Factorial and Basic Permutations

n! = n × (n-1) × (n-2) × ... × 2 × 1
ⁿPᵣ = n!/(n-r)!
ⁿPₙ = n!

Special Permutation Cases

Repetition allowed: nʳ
Identical objects: n!/p!
Multiple identical groups: n!/(p₁! × p₂! × ... × pₖ!)

Circular Permutations

Clockwise ≠ Anticlockwise: (n-1)!
Clockwise = Anticlockwise: (n-1)!/2
Circular ⁿPᵣ (different): ⁿPᵣ/r
Circular ⁿPᵣ (same): ⁿPᵣ/(2r)
