The left window will have permutations of the 4 fiction books, so the number of possibilities for that window is..

Answer 1

The right window will have permutations of the 3 non-fiction books, so the number of possibilities for that window is

permutations = 3! = (3)(2)(1) = 6

 

Any of the 24 displays of the left window could be combined with any of the 6 displays of the right window, so the total number of configurations is 24 x 6 = 144
