i work there hahaTo be uploaded here. I will initially only do Q15 and 16, and then complete the remaining questions tonight when I return home from an event.
Am currently at Mittagong Maccas if anybody wants to drop by!
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).no need to do the last part of Q16 because it was in the 2014 BOS Trial
