whoever did not understand this read below let me ask you a question, if you are sitting on any of the 6 chairs arranged in circular, which particular chair are you sitting on most important in this is the word "ways" lets understand what is meant by "ways" one person wants to seat in a chair among six chairs arranged in straight line Q:what are different ways to do so? way 1: SNNNNN //he is sitting on 1st chair way 2: NSNNNN //he is sitting on 2nd chair way 3: NNSNNN //he is sitting on 3rd chair way 4: NNNSNN //he is sitting on 4th chair way 5: NNNNSN //he is sitting on 5th chair way 6: NNNNNS //he is sitting on 6th chair Ans: so there are 6 different ways he can sit on a chair. now when it comes to circular arrangement of chair what are different ways a person can seat on a chair? way 1: SNNNNN /he is sitting on 1st chair way 2: SNNNNN /he is sitting on 1st chair way 3: SNNNNN /he is sitting on 1st chair way 4: SNNNNN /he is sitting on 1st chair way 5: SNNNNN /he is sitting on 1st chair way 6: SNNNNN /he is sitting on 1st chair confused right, circle does not have a starting point,the thing is whenever that person chooses a chair and seats on it,that particular chair itself is the first chair thats why its always going to be "SNNNNN" which is the only one "unique" way that he can sit. ans: one way conclusion: in linear arrangement of chairs whenever a person sits on a particular chair his chair is being referenced from the first chair eg. he is sitting on 3rd chair or he is siting on 5th chair this way we have 6 different ways # but in circular arrangement whichever chair he sits on is the first chair itself bcz there is no start point in circle for reference to say that he is sitting on 3rd chair or 4th chair and so on.

Poor explanation seriously!! Why 1st person sits in 1 way when it has 6 choices? No logic!! Lemme make u understand the reason. Consider 3 men ( a,b,c)... How they can be seated in a circular table? 3! (No, Lmme show you those arrangements and why not 3!) 1) b a. c 2) a b. c 3) b c. a.

Finally found someone who makes concepts their base to teach! Thanks a lot.
These videos(specially 15 videos in this channel) are best way to learn in depth understanding of basics of permutation and combination. Don't Memorise has done commendable job in explaining from scratch .
This is the math I like, thoroughly explaining it, not like bombarding us with so many different formulas and not even explaining it. THANK YOU SO MUCH♥️♥️♥️
That is such a mind blowing explanation. I cannot describe in words how to thank you; because words like "Thank you" won't be ever enough for such a valuable service you are giving to million of students like us. May you live long healthy and prosperously. ❤️😇

thankyou sooooo muchh i really needed this '
Madam I like this very much I have seen all videos of other channels but I can't understand that what is happening.but I have learnt from your video . Thank you very much Mahadev har
really very nice videos ... and a very good way of explaining the concept
in case of linear permutations, we consider the things which are to be kept together as one element and then subtract it from the total no of arrangements to get the no of the arrangements when those things are not kept together.but in case of circular permutations, why doesn't this work?
amazing video...thank you so much for making this
