Hi!
Can anyone explain the answer to this question? Chat GPT died while trying. TIA!
Share your approach to this first.
“the first one is a biography” - is that even possible?
Correct, that would imply that two novels have to be with each other. Still, if my calculations are correct, then it would be n!(n+1)!
which indeed is the same as option D - you can show this by writing (n + 1)! = n! \times (n + 1).
