How to prepare for this chapter – Permutation and combination Class 11
Teen-friendly tip time! 🧠
- Skim first for concept: Flip pages 1–4 to understand factorial and counting principle.
- Memorize formulas: Spend 30 minutes reviewing the summary table of nPrnP_r, nCrnC_r, and relationships.
- Do solved examples: Rework the solved questions on pages 5–10 by yourself—cover up the answer and try.
- Practice previously asked questions: Use examples drawn from NCERT, Exemplar (like numbering, team selection, restricted arrangements) (SelfStudys).
- Self‑quiz with revision tables: Use the tables on pages 14–15 for quick daily recall.
- Time yourself: Try solving 3–4 problems in 15 minutes to boost speed before the exam.
- Fun fact hacks: Remember the shirt‑pants example (6 ways) and team selections to link formulas to real life.
Important Formulas: Permutation and combination Class 11 Solutions PDF
| Concept | Formula | When to Use |
|---|---|---|
| Factorial | n!=1×2×…×nn! = 1×2×…×n | For nPr,nCrnP_r, nC_r calculations |
| Fundamental Counting Principle | Total = product of independent choices | Multi‑step selection problems |
| Permutation | nPr=n!(n–r)!nP_r = \frac{n!}{(n–r)!} | When order matters |
| Combination | nCr=n!r!(n–r)!nC_r = \frac{n!}{r!(n–r)!} | When order does not matter |
| Relation between permutations/combinations | nCr=nPrr!nC_r = \frac{nP_r}{r!} | To switch between formula types |
| Repetition not allowed | Adjust factorial accordingly | E.g. 4‑digit numbers from 1–9 without repetition |
| Circular permutations | (n–1)!(n–1)! | Arranging around a circle |
Previously Asked Questions from This Chapter
These are the classic bullet‑list topics that appear often in CBSE and Exemplar:
- Finding number of permutations of r objects from n distinct items → nPrnP_r
- Selecting teams, committees, subgroups from a group → nCrnC_r
- Problems combining inclusion/exclusion, at least one clause (draw at least one black ball) (ncert.nic.in)
- Forming numbers without repetition (4‑digit numbers from digits) (ncert.nic.in)
- Restricted permutation (with or without certain persons) (ncert.nic.in)
- Circular arrangement vs linear (circular = (n–1)! )
- Identical objects permutations (e.g., letters or objects repeating)
