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.

    हल किया गया उदाहरण

    How many ways can you choose 3 items from a set of 10? (Order does not matter)

    1. C(10, 3) = 10! / (3! × 7!)
    2. = 3,628,800 / (6 × 5,040)
    3. = 3,628,800 / 30,240
    4. = 120
