Did anyone get the number of statues that had to be made as 18?
Yep, 18, but then again I just got completely and utterly raped.

I got totally ripped apart.

All that practice I had done in preparation for this exam flew out the door.

Ya I did. Trial and error yeah?
i did it by using a table in graph and tab and got 18
Same thing, same thing. All good though.

X~Bi(n,.20)
Pr(x>=2)=0.90
Pr(x<2)=0.10
Pr(X=0)+Pr(X=1)=0.10
(n 0)(.2)^0(.8)^n + (n 1)(.2)(.8)^(n-1)=0.10
(.8)^n + n(.2)(.8)^(n-1)=.10

Solve for n using CAS
n=17.9479
~~18.

Should be right...>.<

Did people think that exam was harder than 2007 cas?
2007 saw 62.5/80 as A+ threshold, can presume hope the threshold is similar this year?

Might just be a bit of post-exam hysteria on my part, but that DEFINTELY seemed harder than any previous VCAA exam. So perhaps the threshold will be around that.

My CAS ruined it for me

Took ages to input the equations

then it left me with "no solutions" and "insufficient memory"

DAMN YOU CASIO
