parisiennegirl96 Posted May 15, 2014 Report Share Posted May 15, 2014 What did you think of paper 2 ? I found it quite easy Reply Link to post Share on other sites More sharing options...
_mjaku:_ Posted May 16, 2014 Report Share Posted May 16, 2014 I was elated during the reading time in the beginning when I realized that the questions were so easy. However, because of that I didn't follow the time as closely as I should've during the exam and panicked when I had only 5 minutes left and I hadn't even started the last question yet. I also had to skip the binomial expansion -thing so I think all the good points I got from paper 1 were lost due to my own bad time management in paper 2.

student24 Posted May 16, 2014 Report Share Posted May 16, 2014 whats the answer to the last question, about choosing at least 25 out of 100 trees, and the probability of it being giant trees.. something like that. I got about 52%, but somehow everyone i know has different answers. What did you get? Reply Link to post Share on other sites More sharing options...

parisiennegirl96 Posted May 16, 2014 Author Report Share Posted May 16, 2014 know i did 1-P(X<24) using th calculator... sorry i dont remember the values Reply Link to post Share on other sites More sharing options...
Guest Arisa Morgan Posted May 16, 2014 Report Share Posted May 16, 2014 I remember that the first probability I calculated of finding if the tree was a giant was 0.191. For that last part, I used binomcdf (since it's cumulative) and used 1-P(x<24) too. I don't know exactly but the number was pretty low, like 0.3 or 0.03.. 2 Reply Link to post Share on other sites More sharing options...
