    LOL. Would you feel brave enough to say that stratified random sampling could be used by dragnetting the entire lake of all the fish?

    I did feel like their choice of wording was overly authoritative for that part. :lol:

    On the other hand, I've been going through an excellent set of probability theory lecture notes from a Harvard course that's really interesting me right now. MGF's/PGF's are really cool. :eek3:

    Is that the equivalent of the worded questions in S2 and S1?

    Neat. Conditional probability is absolutely fundamental in modern probability theory.

    Handy Tripos Hint: Learn how to do conditioning arguments; so many apparently difficult problems melt into nothingness if you condition on the right events.

    Aye, I had originally skipped the first 18 or so lectures and got my teeth straight into bivariate stuff and MGF/PGS because I figured I knew all the before things. He brought up a conditional problem and I understood none of it so I went back to the beginning and I'm going to try and understand conditional probability because at the moment. I don't understand it at all.

    Can't I just fish and decide which one's healthy and which one isn't?

    STEP III, 2009:

    Time: 3 hours
    Mark: 118

    General thoughts: I really, really liked this paper. Hence the one-off high-mark fluke. There were two limits questions, integration questions, induction/polynomial one, Laplace transforms, Fresnel integrals, all stuff that are unfamiliar to people and are, as such, made rather easy but due to my familiarity with those sort of things, I found it rather easy. Which is unfortunately, unlikely to happen in the real thing.

    Q1: Started with this and even though it looked a little daunting, once I put pen to paper it came out within 20 minutes. Full.

    Q3: Decided to do this once next because Q2 looked a little lengthy. This was an absolute gem, I could see exactly what I needed to do for each part and it all fell out within fifteen minutes. Full.

    Q4: I kept putting Q2 off because all the other questions looked so fun, especially this one. Again, it was pretty obvious what to do in each case and I squeezed a full out in 19 minutes.

    Q2: Finally went back and got this done. It took fairly long and I reckon I didn't justify myself too well at the very end. So 19/20 in 24 minutes.

    Q7: This one was fairly lengthy as well and I didn't do the very last bit about the degree of the polynomial which is apparently worth a fairly large amount of marks. So 15/20 in 25 minutes.

    Q12: Now that I'd gotten 6 fulls I started relaxing my criterion for picking questions (I had an hour left on the clock), I spent about half an hour on this stats question which was quite interesting. I'm getting a hang of this PFG stuff.

    Q5: Now that I'd gotten 7 fulls I started going through the pures again and attempted Q5. Not much to say about this, I scribbled out the horrid mess of algebra as quickly as I could and that was that.

    I might have a chance of meeting my offer after all. Hopefully, gotta keep this up. I have a feeling my next mock is going to go downhill from here.

    Wtf? You're S'ing all your mocks and you were doubting that you'd make your offer?
    That's like me saying that I might not meet my offer lol.

    It's just all so unpredictable and I really don't wanna get my hopes up, if you get what I mean?
