I've been taught Bi, though HSC uses B.

This is 3 unit binomial probabiliy. Set up a binomial distribution in the form X~Bi(n,p) then use the formula P(X=x) = nCx × (1-p)^(n-x) × p^x. Whats so hard is that its very worded and you need to apply different conditions for each situation, as given byhe question. Although this may not be...

Thank you! Would you possibly know yet if the exams will continue this year and when enrolments might open? I am looking forward to them!

Last question before I go (sorry), can you take a reference sheet?

Okay, thank you for your help!!

In what way could the syllabus change this year?

Its a lot more complex. You have to prove completion of Stage 5 content, then your school proposes the case to NESA who gives them a yes or no, then your school sets a program and begins. Unfortunately with the current circumstances, it has made things alot more difficult. I would prefer to...

Currently, I am in Year 9 but my school cant open up resources for acceleration at this level. They are definitely working for it for next year though. Ill just gain experience from the years I miss so Im not too disappointed.

I think they are going to kill the vectors topic - perhaps introduce matrices during the exam and look at the cross product. Definitely think they will ask to prove dot product in relation to area, and will have a 3D killer geometrical proof. Im thinking to enrol - are you allowed to do these...

I just checked - it is lol

Didnt you say this years exam enrolments havent opened?

Thank you so much for your time!!! Ill definitely consider this challenge. Did you do the test this year or last year?

Sorry, and can you take this if you are not in year 12?

Where are they usually taken?

Have this years enrolments closed, and do you get the paper back? Thanks!!

Where are these exams taken, and how do you enrol? Ive always been interested!

You could treat a b c as roots to a cubic polynomial then make a statement from that as well. True, under pressure is different.

Couldnt you just solve for a, b and c from the equation abc = 1 then substitute, simplify and justify? If you are allowed to post this test later on, that would be great!

Could you provide a copy?

You could go into complex numbers and use Taylor series expressions for real and imaginary part, then you could prove local finite integer ABSOLUTE convergence from a point, calling z_n = M^n + M^(-n) and by proving that |Re(z_n)| and |Im(z_n)| ==> |z_n| converges. Type of approach from complex...
