SOURCE: how do i enter the formula into my calc for a

This is for the TI-30 XIIS. It should work for you once you find the (nCr) key or the menu item under PRB key. If you know the formula skip to Exemple

Let us start with a review of the formula for the binomial distribution

But n!/(r!(n-r)!)=(nCr) you get
f(r;n,p)= (nCr)x(p^r)x(1-p)^(n-r)

Exemple : n=25, r=6, p=0.7

f(6;25,0.7)= 25 [PRB] [-->] 6 [ x ] {0.7[ ^] 6 }[ x ]{0.3[ ^ ]19}

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.
[ ^] is the raise to the power key
The { } are used here as parentheses to make formula legible.

Hope it helps

I am trying to add/subtract & multi/divide with a TI 30XS. I can't close the parenthesis. I'll enter the number, then x10n, the exponent, but when I try to close the parenthesis it display

Are you opening the parentheses in the first place? If you don't have a left parenthesis then you don't need a right parenthesis.

Could you post the exact sequence of keystrokes you're using?

I'm having troubles with parentheses. How can I enter: 2-(-2) ?

Most likely you're having troubles with the negative sign, not the parenthesis.

Press 2 - ( 2 +/ ) =
The "+/-" key is the key just to the left of the "=" key, used to enter negative numbers.

For this problem you don't need parenthesis. You can simply press
2 - 2 +/- =

Light on dash came on which says "IP Brake" After 21/2 hrs. at the mechanics they couldn't figure it out except to say it has something to do with the ABS system

All your saying, is that the shop you went to, has no reference
material or data base, to even know what to check on your truck

If you have the factory manuals from, you could possibly
figure it out

I won't guess, it is an obd1 system,pre 1996, so it can't be all
that hard

All you can do, is start to research for a shop in your area, that
that is good at everything. I would ask around for a couple weeks,
and then build a relationship for years to come.

I have a TI-30XS Calculator and cannot figure out why the thing won't work when I try to divide numbers with scientific notation. The calculator appears to be adding exponents when it should be...

One solution that you might try is to put the scientific numbers in parentheses. For instance open parenthesis, type in the first scientific notation then close parenthesis, next hit the divide key and then open parenthesis and type in the 2nd number in scientific that you are dividing by and then close parenthesis. Hit enter or =. I'm not sure if this will fix your problem, but it is worth a try.

Stuck at 288 degrees


After a power outage, my wife's grandmother said she could no longer set her over to 300, 400, 450, whatever..

I went over to troubleshoot.

I couldn't figure out why everything seemed functional and why I couldn't set the over to higher than 288 (and thought, that's a rather odd number)... until I realized that that 288 degrees C = 550 degrees F which is the max the oven can do.

The power outage reset the computed back to celcius instead of fahrenheit.

Save them a ton of money... cause this could have been an easy cash grab to some cook out there.

Dividing by a negative exponent

(2x3^2) divided by (2x3^(-2))
just make sure to use double parenthesis around the negative exponent so that you get the right answer
