This is a shot in the dark but it may be to do with some s1 exam cancellations yesterday because of snow?

Idk though I mean we're discussing it here now anyway
nah, nothing to do with it. Edexcel Maths papers are international exams. It went ahead at the vast majority of centres. If it was cancelled at a particular centre then it is just bad luck for those entered there.

They were never cancelled. Even if cancelled, you can't sit until may/june

For the one about working out the standard deviation, i completely forgot they gave you Sigmafy^2 and worked it out from scratch, talk about wasting your time !_!
Wooow I didn't even know it was possible to work out sigma from what they gave although you didn't need to well done for being able to do it

I posted them at 7:30 but the thread is still waiting approval. I just tried to start another thread now but again it saying in needs approval from a moderator. Really not sure what is going on.

If it takes 2hrs for a thread to be approved every time I am just not going to bother posting the solutions anymore.
I suspect this is an automated system to prevent embargo breaches for Edexcel. If you want to avoid this in the future, do what you used to do and start an empty thread in advance and tell me. I will close it and sticky it and then open it for you as soon as the embargo ends.

Ha, we were thinking the same thing. I basically said if Tom got 2, which die she should pick and the probability of her winning with that die. Did the same when for 5.

How did you get the 5/12? I did (probability of 2 on coin) x (probability of getting 3 or 5 on die) + (probability of getting 5 on coin) x (probability of getting 6 on die) which I think came to (1/2)x(2/3) + (1/2)x(1/6). Does that that sound about right?
