    Anyone have a clarification of that Standard Deviation part? I said that it would increase as the new mean would be older/younger than the previous means. Anyone one side of the previous means would not necessarily be any closer to the new mean and anyone that was the other side of the original mean is now even further "deviated" from the mean. Does that make sense. I think I explained it better this morning :o

    I thought it was pretty handy. Circle question caught me for time though :( (took about 35 minutes), took about 2 pages of horrible grunge till I realised I only need 3-4 lines to finish it. The c) parts in probability and vectors were way easier than I'd expected (finished 3 probabilty questions in 40 minutes :P)... but that's usually not a good thing.

    I got something like that. But I rewrote the vectors to a simpler one, but still ended up in the same place...
