In the book, it solved this question assuming order is important, why did the book assume that? what hint did the question give to assume order is important?
I have difficulties in deciding if order is important or not when its not stated clearly in the question.

The question is about arrangement, so order matters.
Had it been selection, order would not have mattered.
so 9*8*7=504
