    Question premutations and fundamental counting principals. Going nuts Please Any HELP!!!

    Permutations are just an application of fundamental counting principle. I also learned that Combinations are just an application of Permutations and the counting principle. Can you say that Combinations are also just an application of the counting principle? THIS IS THE WHOLE QUESTION, HELP ME!!!PLEASE..

    Greetings:

    A combination is an n-tuple that does not discern order. For instance, (2,3,5), (3,2,5), (5,2,3) are three ways of expressing the same combination of the numbers 2, 3 and 5. By contrast, if order is important, (the order in which you write the digits in a zip code is, for instance, is important), the n-tuple is referred to as a permutation. With regard to your assertion connecting counting principles with combinations, I suspect you may have in mind the means by which we count all possible combinations on a given set taken, say, 3 at a time, as was the case in opening exaple. Indeed there are (10)(9)(8)/((3)(2)) ways of writing (combinations of) the ten digits 0,1,2,...,9 taken three at a time. If you can be more specific in your questioning, I can, perhaps, be of more assistance to you.

    Regards,
    Rich B.

    You can say that premutations is just an application of the counting principle yes. But to say that combinations is an application of the counting principle is wrong.
