How to use it
- Insgesamt n = 10, choosing r = 4
- Apply formula: C(10,4) = 10! ÷ (4! × 6!)
- Simplify: (10×9×8×7) ÷ (4×3×2×1)
- Berechnette: 5040 ÷ 24 = 210 combinations
Common mistakes
- ⚠️ Using permutations Formel instead of combinations
- ⚠️ Not simplifying factorials before calculating
- ⚠️ Confusing combinations with permutations (order matters)
Worked example
Berechnette the number of combinations when choosing 4 items from 10
The combinations {comb} count the number of ways to choose r items from n when order doesn't matter
