First one's right, second one's wrong.

binomcdf(n,p,x) = Pr(X ≤ x)

You had the arrow the other way. But cool that you've looked into it.

kido_1:
Binomcdf is usually used with the terms 'at least' (1-binomcdf...)

Binompdf is usually used for exact. For instance 3 out of 5.

bilgia:
does everyone have 'prcheat' the calc program??? its a time saver, especially for multi choice qns

Toothpaste:
I only have Factor 9 .. cbf putting 10 on. Lol.

Is Prcheat necessary?..

bilgia:
pr cheat is very easy to use
u have options binomial, normal, std normal etc...
and then u input mean, s.d, no of elements etc...
and then u can choose >,=,>=,<= and so forth...
no need to manually do anything
