A game has to be made from marbles of n colors, where n marbles has to be kept one upon another. In how many ways these marbles can be arranged?

Is the answer is $1$ if $n = 0?$

    Th number of ways to arrange 0 marbles is $1$. Yes. However I have absolutely no idea what "A game has to be made from marbles of n colors, where n marbles has to be kept one upon another" is supposed to mean. That sentence does not make any sense to me. – fleablood Dec 10 '18 at 00:33

Yes, there is one arrangement of no things. Sometimes it is a special case if you are making a recurrence relation, but often not.
