This will be my final exam for the year. I'm pretty sure I only got Bs for C1 and C2, but I did a mock for S1 last week, and left after 53 minutes, rather than staying for the full 113 minutes, and I got 92%. I feel pretty confident for this one.
I feel i didnt do as well as I would of liked. Definitely should of done more past papers! Oh well. Hardest part was Q6 I believe. The one about him having 8 shots. I couldnt work out the profit for the life of me! ended up guessing -£5

I hated that question! I had -£1.61 which I thought must be wrong because its a loss not a profit :/
Overall I don't think it was a terrible paper but there were quite a few questions I couldn't do! The profit question, the one when she didn't have a proper calculator, why e(y) isn't poisson?
how did you get this value?? i thought it must be -£5 too because the highest probability was for X<2 so no prize? :/
Yeah I got -£5.00 too. It sorta made sense as the mean number of times that he hit the target was 0.96 -8 times 0.12 (i think)- therefore he fell under the X<2 category so would have made a loss?
Felt like it was reasonable but I messed up the continuous random variables question because couldn't get k=1/2 or whatever it was. Got 1 as the Median which is definitely wrong. Think I got the next two parts of the question though.

It was k(x^2 - x) between 2 and 1. I put 2 in and had k(4-2)=1, 2k=1, k=1/2.
