True. I'm specifically referring to chapter 14C from the Cambridge textbook. It's pretty much all CAS work but my friend is saying it has been removed from the course for this year.
In this case - there's nothing that has been removed from the study design relating to the binomial distribution. So technically, no, it hasn't been removed. I'm going to be honest, I don't remember having seen these types of questions being asked for a while (although S_R_K is probably a better judge of that than me), so if you're that worried, feel free to take the gamble. However, they're also not that hard, it's just different thinking - so could be worth learning that section so you get the new way of thinking.
how would i convert an equation from slope-intercept form (y=mx+c) to standard form (ax+by=c) using ONLY cas (tinspire specifically)? i know it's often easier to do this by-hand but....just in case
I don't know of a CAS function that can do this, but I cannot think of a single instance you'll be required to do this on a CAS and not in your head or on the page. All you do is multiply both sides by the denominator of m, then by the denominator of c, then move the x term to the other side. TBH, if the question asked (and I can promise you - VCAA will never ask this) you, "Convert y=(5/6)x + (2/3) into standard form using only your CAS", you should be able to do that in your head and just write, "by CAS, 18y-15x = 12". It's not like you submit your calculator for inspection after the exam, so.
Perchance there's a situation you imagined in your head you might need it for, and I might be able to help assuage those fears?
