    He was talking about using the probability of mutliplying to get an odd to find the probability of getting an even i.e 1-[P(YxZ)=odd]
    Yehh it's what I did but missed out the 3 times 3 case in the odd so didn't get the right value. So frustrating making mistakes like that!

    We were the group that presented first. I fell asleep in the presentations Was just so tired.
    Yep I was asleep for all of them as well. We probably would have won if it wasn't for a few technical issues with our presentation

    Were you in the team with Westminster? They were pretty good.
    Don't think so. We came second but at least half our stuff didn't make it on to the slides due to some issues so with that we would most likely have won

    The boundaries are amazingly low... for everything but maths Maths is just painful
    Seriously? Not even basic stuff, matrix multiplication and all? Complex numbers isn't hard but the questions can be such a pain

    I live in Tanzania
    Ohhh Tanzania :cool:

    Yeah it was the same with IGCSE and I always wondered whether the CIE candidates are all amazing at maths or not :dontknow:

    Nope lol Having find IGCSE one of the FM chapter was a breeze because it was just matrix manipulation

    Nothing wrong with a tree diagram. I just like skipping steps especially since the less steps the less chance I have of doing something stupid

    That's true. It's always good to be confident at two different methods though, so you can check your answers

    Yep always good to be able to check your answers. Thankfully for things like c2 I can type most things into my calculator and check that they are correct eg my calculate can do definite integration

    Yeah it's a graphical one. Super useful but I only use it to check answers. Can't get full marks by just writing the answer down lol

    I didn't really want a graphic one. They are too big and expensive and can't do anything mine can't

    Mines not graphic either but it can do definite integration, equations involving complex numbers and inverse of 3X3 matrices which is so so useful for fp1. Definitely worth checking all its hidden features, could make the difference aha

    Definitely will be, maybe over the summer haha. I have a friend who knows like everything about the calculator, and he's doing FP1 this year, so I might get some tips off him next year

    Haha, I think we should stop playing the 'my calculator is better than yours' game. :lol: But yeah, the fact that it's graphical is useful because you can see what the equation in question looks like.

    It was only £30 for me so it was just better to get that anyway

    On the plus side, you can have calculator races if you know how to get to it. Perfect for when your bored in exams.
