But if we wrote:

Quote
binomcdf(10,1/6,4,5) = 0.0672897

Does that count as a method mark for CAS?

So are you expected to write out the full working out for Pr (X=4) + Pr (X=5) to get a Method mark?
So like xCn (p)^n (1-p)^x-n?

No you will get ZERO for the question, despite your answer being correct.
VCAA, around April-March this year, sent emails to many maths teachers,
across Victoria, explaining this exact issue.

So what about in normal Methods?

So I'll have to do it /0's way to get the method marks?
