Nope, it was exactly 5514. You would have gotten an inaccurate answer for rounding off your value of s.d prematurely, maybe.

Yeah the s.d was 6.063... I rounded it up to 6.06 and so got 5508.5 instead of 5514, I just retried it.. :/

How many marks would I lose for that? :s

Yes, it is indeed correct. The correct answer was supposed to be 0.368, and it gives exactly that.
I made a horrendous error. What I did was write 4C2*(18/30)*(17/29)*(12/30)*(11/29) and got the answer 0.320. I must have been blind or something. Do you expect I'd get any marks out of 4? 2 maybe?
Why didnt you just use the combination method? Its usefull for questions where there's no replacement.

Example - (4C2 * 8C3) / 12C5

Just an example, I dont remember the values in the paper to write the exact answer.

CRV in my book is just the prob density function, I think you mean a different chapter. Give me a question for example and I'll explain from there.
