## How to Calculate Combinations
### Formula
**C(n, r) = n! / (r! × (n - r)!)**
Where:
- **n** = total number of items
- **r** = number of items being chosen
Combinations count selections where **order does not matter**.

Esempio Risolto
How many ways can you choose 3 items from a set of 10? (Order does not matter)
- C(10, 3) = 10! / (3! × 7!)
- = 3,628,800 / (6 × 5,040)
- = 3,628,800 / 30,240
- = 120
