got n=36 literally did every past paper since 2008 and this was by FARRRrr the hardest 1. Sampling distributions of the range are not even in the text book!!!!

My teachers (who had the paper afterwards) said they were unsure as to whether the last question was x-b(10,0.6) or x-Po(6) so i reckon they are both going to be right (I did binomial btw)
it had to be binomial didn't it? because there was no reason for it to be Poisson?! n isn't too large for the tables and p isn't small? or i could be really wrong here!

At some point, I remember getting the value 0.8088 for one part of the question and squaring it for the next part. if this means anything to anyone

I did P(X>1.5) + P(X<2.5)...

I hope someone would post solutions!
I didn;t do ur way. I did the first method. Would I get any marks at all. cuz I just have to 1 minus that to get 81/128
