Question 549939
you have 4 different works.
on a shelf, they can be arranged in 24 ways.
using the permutation formula, this works out to be:
4! = 4*3*2*1 = 24
each of the 3 volume works can be arranged in 6 ways.
using the permutation formula, this works out to be:
3! = 3*2*1 = 6
each of the 2 volume works can be arranged in 2 ways.
using the permutation formula, this works out to be:
2! = 2*1 = 2
for each of the 24 possible arrangements of works, you have 6 * 6 * 2 * 2 possible arrangements within each work.
this comes out to be 24 * 6 * 6 * 2 * 2 = 3456
