**Is it possible to count the number of combinations?**

### How do you find the number of permutations and combinations?

Example 1: Find the number of permutations and combinations if n = 12 and r = 2. Solution: Given, n = 12 r = 2. Using the formula given above: Permutation: n P r = (n!) / (n-r)! =(12!) / (12-2)! = 12! / 10! = (12 x 11 x 10! )/ 10! = 132. Combination:

**What is the formula for combinations in math?**

The formula for combinations is: nCr = n!/ [r! (n-r)!] What are the real-life examples of permutations and combinations? Arranging people, digits, numbers, alphabets, letters, and colours are examples of permutations.
