How do I use the random number generator to generate numbers between 1-100 or 1-10

The RAN# button generates a random number between 0 and 1.If you want to flip a coin, see whether the generated random number is less than 0.5. Alternatively, multiply by 2 and see whether the integer portion is 0 or 1.If you want to flip a die, multiply the generated random number by 6, add 1, and ignore the fractional portion. This will give you a number in the range 1 through 6. A similar method will allow you to generate random numbers in any range.

The random number function always generates a number between zero and one. You can convert this to a random number in any range by a suitable combination of multiplications and additions. For example, if you want a random number between zero and ten, multiply the generated random number by 10. If you want a random number between one and ten, multiply the generated random number by 9 and then add 1.

If you want to simulate the roll of a six-sided die, multiply the generated random number by 6, add 1, and ignore the fractional portion. This will give you a 1, 2, 3, 4, 5, or 6 with more-or-less equal probability.

The post answer the question concerning how to generate random integers. The example given is for rolling a dice. I am inserting the modification that treats your case at the end.

The random number generator function is called Ran# and can be accessed in RUN mode by pressing:
[OPTN] [F6] [F3] (PROB) [F4] to access the (Ran#) function
In the paragraph above, the bold text in square brackets indicates keypresses, while the text in parentheses represents the menus that appear at the bottom of the calculator screen. This also assumes there are no menus on the bottom of the screen when you begin. If PROB is already on the screen, then the [F6] key is not necessary, just press [F3] then [F4] at this point.

The Ran# function generates a random decimal number between 0 and 1. If you need to generate a number with a higher range, then there may be extra steps involved. For example, to choose a random number between 0 and 100, you would enter:
Ran#×100 or Ran#(100)


Let's say you want to simulate a dice roll, where you get an integer between 1 and 6. Your first step would be to do:
Ran#×6
This will give you a random decimal number between 0 and 6. But we need an integer, not a decimal. To make it an integer, you would change this to:
Int(Ran#×6)

Press [OPTN] [F6] [F4] (NUM) [F2] to access the (Int)

This now gives you an integer between 0 and 5. We just need to add 1 to the result.
Int(Ran#×6)+1
The result should be an integer between 1 and 6.


To generate random number between 1 and 50
Int(Ran#×50)+1

The random number generator function is called Ran# and can be accessed in RUN mode by pressing:
[OPTN] [F6] [F3] (PROB) [F4] to access the (Ran#) function

Hello,
To access the Random number generator, press [MENU], Use arrows to select [RUN] and press [EXE].
In [RUN] press [OPTN][F6:->] to pan to the right then press [F3:PROB] then [F4:RAND#]. The command echoes on the screen.

1. Now if you press [EXE] a number between 0 and 1 is generated.
2. Each time you press [EXE] a new number is generated.

Although it is not documented, I found out that if you enter RAND#(n) where n is an integer, it generates a number between (0 and n)

Hope it helps.

A random number generator exists on this calculator. It is accessible in RUN or PGRM modes by pressing the OPTN key. If you don not see a tab PROB at the bottom of screen, press the rightmost key to move to next page.

Anyway, RAND# generates a real number between 0 and 1.

For other numbers read on.

Hello,
Turn calculator ON, press MENU if you see no icons. Use arrow key to highlight the RUN application. Press OPTN, press F6 to pan right. Press F3: Prob, then F4:Ran# then EXE to execute.

Each time you press EXE a new random number is generated. You might want to fix the number of decimal digits to less than the 10 digits displayed by default.

By default number generated are between 0 and 1. If you want numbers between 0 and 100 you enter Ran#(100).

Hope it helps.

Press the math key. Arrow over to PRB (probability) Select #5 randInt. You will now be at the home screen. From here you have to let the calculators the set of numbers you want to use. For example if you want to use the numbers 1 thru 50 type in 1,50. You must separate the numbers with a comma. Then press enter as many time as you want to generate a random number. It is not necessary.to end the parentheses.

Random number generators on computers are not really random. They need to be "seeded". If you seed the random number generator with the same seed each time you will generate the same list of numbers. A common technique in computer programming is to seed the random number generator with a value like the number of seconds that has occurred since midnight. This gives you the illusion of real random numbers.

Look up the word "Seed" in your calculator documentation and it will most likely tell you how this is accomplished on the TI calculators.
