Stats 2 (S2) OCR (not MEI) 22nd June 2012
It's been a while since you posted and nobody's replied yet...maybe you should check out MarkedbyTeachers.com, TSR's sister site. It has the largest library of essays in the UK.
They've got over 181,000+ coursework, essays, homeworks etc.. all written by GCSE, A Level, University and IB students across all topics. You get access either by publishing some of your own work, or paying £4.99 for a month's access. Both ways give you unlimited access to all of the essays.
All their documents are submitted to Turnitin anti-plagiarism software, so it can't be misused, and the site's used by hundreds of thousands of UK teachers and students.
What's more, you can take a look around the site and preview the work absolutely free. Click here to find out more... -

Re: Stats 2 (S2) OCR (not MEI) 22nd June 2012There seems to be a common pattern emerging among people who sat that exam... they all hated it(Original post by etothepii)
can't imagine any exam going worse than that FP2 paper, tbh

Re: Stats 2 (S2) OCR (not MEI) 22nd June 2012If the A* pupils hated it, I cannot imagine what sort of student liked that exam(Original post by wibletg)

Unfortunately, I'm the only one doing FM from my school so I was under the impression that I'd done extremely badly until I saw the rage on TSR

To be fair, our year is unusual in that 10 people are taking it to A2 - last year there were only 2
Yeah, there was quite a bit of nerd rage. It should be interesting to see the boundaries in August

Re: Stats 2 (S2) OCR (not MEI) 22nd June 2012I don't think we've ever had more than 5-6 people take it, even at AS.(Original post by wibletg)

Doing Maths at uni, I'm guessing? -

Our school focuses more on Mechanics modules because the FM teacher did Physics as a degree, so we've got 5 engineers, 1 computer scientist, someone doing economics, a physicist and the only person doing maths

Re: Stats 2 (S2) OCR (not MEI) 22nd June 2012Oh, I see. I'd have loved to do more mechanics modules but one of our two FM teachers did Stats so I ended up doing S1-S3, lol. tbh, S1 was the only tedious one; I found S2 and S3 slightly more interesting, especially the latter.(Original post by wibletg)

Re: Stats 2 (S2) OCR (not MEI) 22nd June 20123 buttercups per cubic metre, so for m cubic metres the distribution of X, no. of buttercups, is x~Po(3m).(Original post by ellie_159)
Can anyone help me on Question 9(iv) in January 2010?
(a) Without using an approximation, find an expression for the probability that in m square metres there are at least 2 buttercups?
Thanks in advance!
At least 2, so P(X>=2)= 1-P(X=<1)
Then use the poisson formula with 3m in place of lambda and you should arrive at the expression they want.
