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.

What is permutation and combination with an example?
Give examples of permutations and combinations.
The example of permutations is the number of 2 letter words which can be formed by using the letters in a word say, GREAT; 5P_2 = 5!/(5-2)! The example of combinations is in how many combinations we can write the words using the vowels of word GREAT; 5C_2 =5!/[2!
How do you explain a combination?
Combinations are much easier to get along with – details don't matter so much. To a combination, red/yellow/green looks the same as green/yellow/red. Permutations are for lists (where order matters) and combinations are for groups (where order doesn't matter). In other words: A permutation is an ordered combination.
What are combination numbers?
What is a Combination? A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.
What is another name for combination?
What is another word for combination?
| amalgamation | blend |
|---|---|
| mix | mixture |
| amalgam | compound |
| composite | fusion |
| meld | alloy |
What is the formula for calculating combinations?
Combinations Formula:
C(n,r)=n!(r!(n−r)!) For n ≥ r ≥ 0. Also referred to as r-combination or "n choose r" or the binomial coefficient. In some resources the notation uses k instead of r so you may see these referred to as k-combination or "n choose k."
How are combination applied in real?
In smaller cases it is possible to count the number of combinations. For example given three fruit, say an apple, orange and pear, there are three combinations of two that can be drawn from this set: an apple and a pear; an apple and an orange; or a pear and an orange.
What is nPr formula?
In Maths, nPr and nCr are the probability functions that represent permutations and combinations. The formula to find nPr and nCr is: nPr = n!/(n-r)! nCr = n!/[r!
How many combinations of 7 numbers are there?
The number of combinations that are possible with 7 numbers is 127.
