Learn and know what is the permutation meaning in mathematics. In class 11 and also for IIT JEE exams permutations and combinations is one of the important chapters and also very interesting chapter.
The meaning of permutation is “arrangements”. I think arrangement meaning everyone knows. Along with the meaning of permutation we should also know its Definition.
Definition of permutation:
Permutation can be defined as “Each of the different arrangements that can be made by taking some or all the things at a time”
If there are 3 digits and by taking 2 digits at a time, how many arrangements can we made? When Repetition is not allowed i.e. the same digit we should not take again.
1, 2 and 3 be the three digits. Now let us take 2 digits from 3 digits and arrange them. We get
12, 13, 21, 23, 31, 32. Here, Each of these arrangements is called as a permutation.
We are not writing 11, 22 and 33 because repetition is not allowed, if it is repetition is allowed then we can write them.
I hope you have understood meaning and definition of permutation.
