You want to arrange 17 books on the shelf of a bookstore.
The shelf is dedicated to the three Toni Morrison novels
published between 1977 and 1987: Song of Solomon,
Tar Baby, and Beloved. You have many copies of each,
but on the shelf you want an even number of Song of
Solomon, at least three copies of Tar Baby, and at most
four copies of Beloved. How many different arrangements
are possible?
