probability of getting a sum of 7 is 1/6 therefore
4C2*(1/6)^2(5/6)^2 + 4C3*(1/6)^3(5/6)^1 + (1/6)^4=19/144 (hopefully)
(I don't have a calculator on me but im pretty sure its right)
I got 94/120 (78%) and i don't think that i'm close to the top of the state, well not yet. I'd think you would have to get like 95% to get close to the top. As for band 6 i really don't know but i think the CSSA trial this year was not as hard as previous tests.
I've never used one but i've heard of them. (http://www.grand-illusions.com/acatalog/info_48.html)
Or you could get a space pen, apparently they last a long time.
Actually 'helper' I think they are different rules but I’m pretty sure you don’t need the left hand rule cause only the right hand rule is in the syllabus.
Also there’s the right hand grip rule where in a current carrying conductor your thumb points in the direction of the current and your...
