why 8C4 instead of 8P4 for S? Arrangements are permutations, not combinations.

Ok, so I'm going to answer my own question. For the S's, the order doesn't matter because it looks the same no matter which S is placed in any of the eight places. Therefore it is correct to say 8C4. It is equivalent to dividing 8P4 by the 4! repeats of S.

Thank you for your videos. I'm looking at coming up with names of products by combining words. Is there a software that would offer all these permutations and combinations please

sir in part b it can also be possible that 2s or 3s are together, as question does not say that all s are together

I have a doubt sir..why we devide the common arrangements from total arrangements instead of substract them

When to take permutations and when to take combinations. In one of the question, you had taken permutations for the different spaces to be filled and here you have taken combinations.

Wrong solution
Wrong combination
It will be 4C8 not 8C4
Hence it cannot be applied here
Answer will be 33810
