4. If someone uploads the paper I probably remember enough S2 to do answers..

yeh nobody seems to be able to get hold of one - by the time someone does get the paper I will probably have forgotten my answers so it won't be of much use -__-

Yeah it is 1.41, that's the only mistake that was made on the answers
What about Q6 a?? Are you sure there was 9 samples, not 6??

Yeah I'm pretty sure it was 9

WHy? isn't it 44 66 88 46 48 68 which makes 6? Especially if i got the second part right, where total probability of these 6 makes 1, which is correct.

Okay, that makes sense now. Thanks
14. How many marks do you think i will lose in Q1 e if i did this?
Y-B(12,0.1378)
P(X=3) = 12C3 x (0.1378)^3 x (1-0.1378)^7 instead of 9, and therefore got the wrong answer

How many marks was it, 3?
you'd lose one for accuracy I'd say

Yes it was 3 marks, but i got wrong answer just because i put 7 instead of 12-3=9, and thought i will lose 2 marks, 1 for accuracy 2 for wrong answer.
