no need to do the last part of Q16 because it was in the 2014 BOS Trial

Also the Year 12 3U Pender Textbook had some extension Q's on derangements, but I can't remember whether they got you to derive the formula for D(n) too (I suspect they did, but they didn't guide you through it as much as this HSC paper).
