Hello,

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

**f(r;n,p)=n!/(r!(n-r)!)x(p^r)x(1-p)^(n-r) **

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 **

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

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?

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 +/- =

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 Helm.com, 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.

Make sure you use the (-) key located just to the right of the decimal point key, not the - key used for subtraction.

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.

NO PARTS REQUIRED!!! DON'T PAY FOR A SERVICE CALL!!!

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.

(2x3^2) divided by (2x3^(-2))

just make sure to use double parenthesis around the negative exponent so that you get the right answer
