**Solve the problem in the comic strip below. Assume that the books are all different.**

There are** 3,62,880 different ways nine books **could be arranged on a shelf.

It is to be determined in how many ways nine books could be arranged on a shelf.

There are a total of 9 books.

When one of the books is put in first place, 8 remain to be put in the next place, then 7, and so on.

By the Fundamental Counting Principle, there are $9\times 8\times 7\times 6\times 5\times 4\times 3\times 2\times 1=362880$ different ways nine books could be arranged on a shelf.

Hence, by Fundamental Counting Principle, there are 3,62,880 different ways nine books could be arranged on a shelf.
