Ti-84 BINOMIAL PDF

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had; Trails: 13 P: 53/100 X Value: L1 (List 1) And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

My TI-84 Plus won't let me graph trigonometric functions.

Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].If it's not the angular mode, please reply to this post and give an example or two.

It is just not working. it is freezing on me?

When you change the batteries the display reverts to default setting. My optimistic guess is that the screen display is so light that you cannot see anything on it. This can be arranged.

A Try this before thinking of repairs.

  1. Push the ON button.
  2. Even if you see nothing, press the [2nd] key and release it.
  3. Press and HOLD the UpArrow key until the screen darkens.
  4. You may have to keep pressing UpArrow for a little while before you see anything.
B If that does not work
  1. Remove one of the AAA batteries.
  2. Press and hold the [CLEAR] key.
  3. Whileholding [CLEAR], reinsert the AAA battery and then
  4. turn the calculatoron.
  5. The calculator should display the message "RAM Cleared".
  6. Release the [CLEAR] key and then press it one more time to remove the message "RAM Cleared".
C. Third option

  1. Remove batteries including the backup battery for 5minutes.
  2. After the 5 minute period, reinsert all of the batteries and
  3. turn the calculator on.
  4. Adjust the contrast if necessary.
D. Last option

The last option requires the reinstallation of the system. So to use it you must download the TIConnect 1.6 software from education.ti.com. You must have the TI USB SilverLink or the TI Black serial cables ready.You must be connected to the Internet.
  1. Remove one of the AAA batteries.
  2. Press and hold the [DEL] key.
  3. Whileholding [DEL], reinsert the AAA battery and then
  4. turn the calculatoron.
  5. The calculator should display "Waiting...Please install calculator software now".
  6. Connect the TI Connectivity cable between the computer and the calculator.
  7. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.
  8. Follow the on-screen directions to reinstall the calculator's OS.
Ifthe message "Error! Press any key to turn unit off. Then turn unit backon." appears on the graphing calculator, quickly, remove one batteryfrom the calculator and reinstall it while the transfer is taking place.

If all else fails you can contact Texas Instruments at [email protected]

Hope it helps.

When ever i turn on

Hi biancaaii,

You need to re-install the Ti 84 Plus OS, ASAP!!! You can fix the problem by installing the newest Ti 84 Plus 2.55v. MP OS. operating system.

If you have a friend that has a Ti 84 Plus or, Ti 84 Plus Silver Edition you can connect the two calculators together through the IO link ports and, they can send you a copy of their OS while you receive it on your Ti 84 Plus. Hopefully your friend will have Ti84 Plus 2.55v. MP OS on their calculator or, it might not work.

If you can't find a calculator to connect to you can connect your Ti 84 Plus to a computer that has Ti Connect software on it. If you need to connect your Ti 84 Plus to a computer make sure the Ti Connect software is operating properly. You do not want any hang-ups while installing the Ti 84 Plus OS. Be careful, even a power failure during the process of installing the OS will destory your calculator.

Procedure 1 to installing the latest Ti84 Plus 2.55v. MP OS

1). You can get the latest copy of Ti84 Plus 2.55v. MP OS and, guidebook by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti 84 Plus 2.55v. MP OS!" Once your at the Ti site click the Download Item, "Ti84 Plus family operating system". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti84 Plus family operating system will download to you.

Next, click "SAVE" and then a window to a folder will pop up. It is probably a window to a folder that you download too. If so, you may want to change it and, save to this folder, "My Documents \ My TI Data \ Downloads". You can also go back and, download the Ti 84 Plus guidebook too, if needed.

Link your computer and, Ti 84 Plus calculator with the USB cable or, Direct Black Link cable that came with the Ti 84 Plus calculator. Next, drag the Ti 84 Plus 2.55v MP OS that you saved earlier in "My Documents \ My TI Data \ Downloads" out of that folder and, drop it in the "Ti Connect" icon on the desktop. Click, "Continue" when the "Erase Warning" pops up and, the new Ti 84 Plus 2.55v MP OS will begin to install.

Next, the Ti Device window should pop up and, highlight the port when it finds what your Ti 84 Plus is using, USB1 cable or, Direct Black COM1.

When the Ti Device Explorer finds and, highlights your calculator's information click, "Select." Then click, "Yes" when the next window shows up with your calculator's information and, the OS will continue to download. Upon completion the newest Ti 84 Plus 2.55v. MP OS will be installed.

If you run into any trouble with software or, drivers just comment to what failed at this posting and, I'll be glad to help you.
