gar i suck at matrices, i have no idea what to do with them haha.

you can still work out the second question according to my method though right?

costargh:
Yep sorry I should have been more clear lol
VCAA 2005 CAS paper which used to allow notes and calc PLUS had a norm distribution cdf table @ the back. LOL

ARGH I just did exam 2 for the VCAA 2005 CAS paper and got a 30/55!!! THAT IS FREEKIN MADDDDDDDDD.... for me which pips me into the 'B' section for that grade distribution

wowwwwwwww im soo happy. I've found motivation . thats 4 exams down in 2 days. now i have to do some more and be ready for this mo-fo

A. -1.960
B. -1.645
C.  0
D.  1.645
E.  1.960

its an inverse probability i think, i remember doing the same question in the 2004 pilot or something.
you say pr(x<c1)=.95 and then inverse it, so you do need a calculator

costargh:
whats an inverse probability?

Galelleo:
I think probability of it not happening
but you need mutually exclusive events?
