Answer 2

ur answer was wrong

Answer 3

You were quite right, Andrew.
The answer should have been
(4!)^4/(4!)²
4! is the number of ways to assemble a single body part.
Since there are 4 body parts to assemble, we have (4!)^4 ways to assemble the 4 people where order counts.

Since there are 4! permutations of the people, as well as 4! permutations of the body parts, we divide by (4!)² when order does not count.

So the final answer is
(4!)^4/(4!)²=24²=576
