A combination is a selection of items from a set where the order is not important. For example, if you have a set of three items, say a, b, and c, then the following are all combinations of two items:
ab, ac, bc
A permutation is a selection of items from a set where the order is important. For example, if you have a set of three items, say a, b, and c, then the following are all permutations of two items:
ab, ba, ac, ca, bc, cb
As you can see, a permutation includes all of the combinations, plus additional selections where the order is important. What is the example of combination? A combination is an unordered selection of items from a set. For example, if you have a set of three items, say A, B, and C, then there are three possible combinations: A, B, and C; A and B; or A and C.
What is the rule of permutation and combination?
There are two types of permutations and combinations:
1. Permutations
2. Combinations
1. Permutations
A permutation is an arrangement of objects in a specific order. For example, if you have a deck of cards, you can arrange them in many different ways. This is known as a permutation.
There are two types of permutations:
a. Permutations with repetition
b. Permutations without repetition
a. Permutations with repetition
Permutations with repetition are those in which you are allowed to repeat objects. For example, if you have a deck of cards, you can arrange them in many different ways. This is known as a permutation with repetition.
b. Permutations without repetition
Permutations without repetition are those in which you are not allowed to repeat objects. For example, if you have a deck of cards, you can arrange them in many different ways. This is known as a permutation without repetition.
2. Combinations
A combination is a selection of items from a set, without regard to the order in which they are selected. For example, if you have a deck of cards, you can choose any combination of cards. This is known as a combination.
There are two types of combinations:
a. Combinations with repetition
b. Combinations without repetition
a. What is an example of a permutation? A permutation is an arrangement, or listing, of objects in which the order is important. For example, the permutation (2,3,1) is different from (3,1,2) and from (1,2,3).
What is permutation and combination with an example?
Permutation is an arrangement of objects in a definite order. Combination is a selection of objects without a definite order.
An example of a permutation would be the five different ways you can arrange the letters in the word "cat":
cat
act
tca
atc
tac
An example of a combination would be the three different ways you can select two letters from the word "cat":
ca
at
ct What is called combination? A combination is a selection of items from a set, where the order is not important. For example, if you have a set of three items, say a, b, and c, then there are three possible combinations: a + b, a + c, and b + c.
