\[4 P 4 = \frac{4!}{(44)!} \implies \frac {4!}{0!} \implies 4!\] @GOODMAN

For first case it would be 5*4!=5! For second case it would be 5*4*3*2 = 5!

I think so

LolWolf Group TitleBest ResponseYou've already chosen the best response.2
Yes to both responses. To check we can show that: 4 people in 5 seats: We can always choose a single person whom is not in a seat, and there are 5 ways to do this, while the remaining 4 get a seat, thus: \(5\cdot_4P_4= _5P_4\), while for the latter, we have, simply \(_5P_4\) as the definition of "permute".
