Looking at the shelf, you see 3 positions:
left, middle and right.
You have choices for a book to place in the left position.
For each of those choices, you would have books left to choose from for the book to place in the middle position.
So far, that would give you different possibilities.
For each of those, there would be different ways to choose the book to place on the right position.
All in all, there are different arrangements for 3 books chosen from a set 7 books.
