There are many random functions on a TI-84 calculator. Find them by pressing MATH, and choosing PRB at the top.
Use rand to generate a random number between 0 and 1.
Example; to generate a random number between 0 and 1, type:
rand
Use randInt( to generate a random integer between 2 integers (inclusive))
Example; to generate a random integer between 1 and 10 (including 1 and 10), type:
randInt(1,10)
Use randNorm( to generate a random number that is close to a certain number.
randNorm(x,y) will generate a number that is 95% certain to be within 2*y of x.
Example; to generate a random number that is 95% certain to be with 2*(.01) of 7, type:
randNorm(7,.01)
Use randBin( to simulate a certain number of trials based on their success rate.
randBin(x,y) will generate the number of trials of success rate y that succeeded if x trials were run. y must be a percent written as a decimal, so it must be between 0 and 1.
Example; to simulate how many trials will succeed if 50 trials are run with a success rate of 75%, type
randBin(50,.75)
An additional number can be added to tell the calculator to generate more than 1 number and put them in a list. These will run the command 5 times and make a list:
rand(5)
randInt(2,9,5)
randNorm(4,.1,5)
randBin(30,.25,5)

How do you connect a TI-83 graphing calculator to a mac laptop so you can enter programming code?
Short answer; you can't. But you can purchase (or borrow) a TI84 calculator and use the TI83's transfer cable to transfer data from the 83 to the 84 to your mac computer (the TI84 comes with a USB transfer cable).
How do you graph an equation in standard form?
On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.
How do you key a cube function into your TI84 calculator?
Either press the carat button followed by a 3 or go to the math function and select cubed.
How do you put Mario on your TI-83 Plus Calculator?
I believe that that isn't possible unless you have it ported to ti84 or you know how to. the file format is different, and the game is built for a separate calc.
Does the TI83 use an operating system?
No. I believe TI83+ and TI84 do use an operating system.
How do you graph x is more than 4 on a TI84 graphing calculator?
Press your Y = button, press X, press second button and then catalog. Press up button to save time and scroll up to > and press enter. then 4. This, >, symbol may be someplace else, but I do not renumber where and all symbols are in the catalog.
Is calculator Ti84 the same as Ti84 plus?
-4
Ti84 and ti85 which one is better?
The TI-85 was the second graphing calculator made by Texas Instruments. (The first was the TI-81). The TI-84 is a much newer version and has more functionality and memory. The only real advantage that the TI-85 has over the TI-84 is that it costs less. As far as where you are allowed to use the calculator, almost every test or class that allows a TI-85 will allow a TI-84 as well. The TI-84 is a much better investment. (If the TI-84 is too expensive, look into getting a TI-83. This model is also newer than the TI-85.)
Which store sells TI 84 calculators?
TI84 calculators can be purchased at retail stores such as Best Buy, Future Shop, Staples and Office Depot. Prices range at approximately $140 and can differ by retailer.
Where can one purchase a TI84 Plus Silver Edition?
One can purchase a TI 84 Plus Silver Edition from the following shops: Amazon, Calculators Direct, eBay, Walmart, Target, eBuyer, Staples, Best Buy, to name a few.
How do you find intersection points on TI84 calculator?
Graph the two lines or equations you want to find the intersection of. Then adjust the window so that you can see the intersection point. (If you don't know where it is, try pressing ZOOM and choosing ZoomFit.) Then press 2ND CALC (above TRACE) and choose option 5, intersect. Use the up and down arrows to select the first equation you want to find the intersection point on, and press ENTER. Do the same thing for the second equation. The calculator will now say "Guess?". Use the left and right arrows to move the x-like shape as close to the intersection point as possible, then press ENTER. The calculator will tell you the intersection point and the bottom of the screen. If you get a NO SIGN CHNG error, then it might be because the intersection point is not on the screen. Change the window so that you can see the intersection point and try again. Also, make sure that your guess is somewhat close to the intersection point.
How do you set Matrix B on TI84?
Press 2ND MATRIX (above x-1). Select EDIT at the top with the arrow keys. The select matrix [B] and press ENTER. You can now edit the matrix. (Use the numbers at the upper right to set the size.)
