The number of different collections of 9 is found from 19C9.$$19C9=\frac{19!}{9!(19 - 9)!}$$

If you are taking only 8 books out of 19 with you on vacation, then why does the question ask for " how many different collections of **9** books can you take?"

If the question is correctly posted, then are you taking a particular set of 8 books with you and one random book for a total of 9, or are you taking *any* 9 of the 19 books with you?
