There is no probability key on the 30Xa as there is on the 30XIIS. The shifted functions of the 8 and 9 keys will calculate the number of combinations and permutations, respectively. The shifted function of the 3 key will calculate the factorial. There is no random number generator.

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 EL-535 can generate random numbers for you. Press 2nd Function, 7. You will see random written above 7 in orange. This will give you four choices for random numbers. 0:RAND - random decimals to 3 decimal places 1:R-DICE -1 to 6 like a standard dice, 2:R-COIN - 0 or 1 and you decide which is heads or tails.3:R-INT for integers up to 99

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.

**Int(Ran#×50)+1**

No such function my ***!

Just click prb --> RAND randint(

If you want a random integer from 1 to ten, randint(1,10

Then you just keep clicking enter to get different numbers.

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.

Hello,

The random number function Rand# generates numbers between 0 and 1. The calculator is not programmable, so I do not see an easy way to make it simulate the throw of a dice.

However if you use Rand#(6) it generates numbers between 0 and 6. You will have to devise a way to discard values less than 1 and introduce the value 6. Maybe if you get a number less than 1 you set it to 6.

It is up to you.

Hope it helps.

Functions on the calculator are **bold**. Numbers you choose are in *italics*.

For random positive integers between 0 and*n* use the following:

**int** (**rand** * *n*) + 1

**int** is on [Math] [Num] F4

and**rand** is on [Math] [Prob] F4

**rand** returns a random number *x* between 0 and 1 such that 0 < *x* < 1.

**int** returns the integer portion of a number such that **int** 123.456 returns 123 and **int** -123.456 returns -124.

For random positive integers between 0 and
