## What is a real life example of a permutation?

What are the real-life examples of permutations and combinations?

**Arranging people, digits, numbers, alphabets, letters, and colours**are examples of permutations. Selection of menu, food, clothes, subjects, the team are examples of combinations.## What is an example of a permutation problem?

Permutations are the different ways in which a collection of items can be arranged. For example:

**The different ways in which the alphabets A, B and C can be grouped together, taken all at a time, are ABC, ACB, BCA, CBA, CAB, BAC**. Note that ABC and CBA are not same as the order of arrangement is different.## How do you solve permutations examples?

For example, let’s say you are choosing 3 numbers for a combination lock that has 10 numbers (0 to 9). Your permutations would be 10

…

^{r}= 1,000.…

**n! / (n – r)!**- N is the number of things you are choosing from,
- r is the number of items.
- “!” is a factorial of a number. (See: What is a factorial of a number?)

## What are examples of combinations?

**A few examples**

- Combination: Picking a team of 3 people from a group of 10. C ( 10 , 3 ) = 10 ! / ( 7 ! ∗ 3 ! ) = 10 ∗ 9 ∗ 8 / ( 3 ∗ 2 ∗ 1 ) = 120 . …
- Combination: Choosing 3 desserts from a menu of 10. C(10,3) = 120. Permutation: Listing your 3 favorite desserts, in order, from a menu of 10. P(10,3) = 720.

## Which situation is permutation?

permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation

**when the order of selection is a factor**, a combination when order is not a factor.## What is the permutation of 4?
