Normalcdf function
Sorry, the TI-30x doesn't have the cumulative normal probability function built-in.

SOURCE: square roots
One way is you get square root by raising to the (1/2) power. For example square root of 16 is
16^(1/2).
You can use this method to get the other "roots" as well e.g. 1/3, 1/4, etc.

SOURCE: how do you divide the denominator into the numerator on the TI-30
Yes, you hit the yellow 2nd key and then the back arrow (it says F D above it in yellow.) It's the last key on the bottom of the left hand row.

SOURCE: How to do nPr or nCr on TI-30x Solar (scientific calc.)
If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.
52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).
8 [2nd][x/y] 3 [2nd][nPr] gives 336
This took me forever to find out, so hopefully it will help someone!
