Sagot :

Well you can arrange [tex]8[/tex] books in [tex]8![/tex] ways, which means it is:

[tex]1*2*3*4*5*6*7*8=40320[/tex] ways

Answer:

720 ways.

You would use 6P6 (Permutations) to find the answer.

You can also use the method that goes like this.

Book 1: 6 possible choices

Book 2: 5 possible choices (as you cannot replace the book once you have placed it.)

Book 3: 4 possible choices

Book 4: 3 possible choices

Book 5: 2 possible choices

Book 6: 1 possible choice (as it is the last book that you have not used.)
