What is the difference between Permutation and Combination?

Answer 1

In permutations, the order of arrangement is very important. In combinations, the order of arrangement is not useful.

Suppose there are two things, A & B;

Their permutations are,
AB & BA;

Their combination is,
AB; (here, AB = BA);

Answer 2

Combinations are the ways in which you can take some things from a larger set without regard to order. This is usually called N (the larger) things taken R at a time.

Permutations are R things taken from a set in different orders. For example, the permutations of the 1st 3 integers taken 2 at a time are
1 2
1 3
2 1
2 3
3 1
3 2.

The combinations in this example would count 1 3 and 3 1 as the same, etc. So there would be 3 combinations and 6 permutations.

Any good algebra book will give you the formula.

Answer 7

The process of selecting things is called combination and that of arranging things is called permutation

Answer 8

ABC is a combination and is the same as ACB, and BCA as a combination. But ABC, ACB, BCA etc. are permutations, where the order of the letters is also important.

All words are permutations of the english alphabet which is a combination of just 26 letters.

Answer 9

PERMUTATIONS
DEF1:an arrangement that can be formed by taking some or all of a finite set of things
DEF2:a permutation is linear if objects are arranged in line
DEF3:a permutation is circular if objects are arranged in form of circle
COMBINATIONS
DEF1:a selection that can be formed by taking some or all of a finite set of things .

Answer 10

Permutation is the arrangement of things, while Combination is the selection of things. always permutation is greater than combination. ex- if u have 10 things...
then permu= no. of ways 2 arrange 10 things
= obviously answer would be more than 10
[bcoz u fix one thing and then arrange the other 9 things, then fix another and arrange the others.........and so on...]

but combi= no. of ways u can select things from 10 things
= obviously u cant select 11 from 10 at once
[bcoz u take'A' and 'C', then u select 'A' and 'B' and so on......]

so i hope it was understandable 2 u...
