# Random Numbers With No Repetition

Jul 25, 2008
I want to generate 12 random numbers between 1 and 75 w/ no repetition.

I was using the aleatórioentre which translate ro "randombetween" function.

But, obviusly, I cant figure out how to make them unique, with no repetition.

I need to be able to create a list of all combinations (where position doesn't matter, therefore its not a permutation) of a list of numbers with repetition enabled. I need to provide anywhere up to at least 10-15 numbers if possible and they are integers normally between 1 and 72. Example: (for numbers 1, 2, 3)

VB:

1

2

3

[Code]....

I am working on a Random Cycle Count Generator that provides random SKU#s based on 3 separate columns of SKU listings. The user clicks a button to generate the SKU#s to cycle count for that day. What I would like to see is a date stamp in the columns next(B,D,F) to the referenced SKU listing(A,C,E) based on which SKU#s are generated. This will let me see the last date that the SKU was generated. I would also like it to automatically save after generating.

I am looking for a way to create a random order of numbers in a given range. For example, A1:a100 to be populated with a random number between 1 and 100, but not to duplicate, using every possible number within that range. I use the RANDBETWEEN function to generate the numbers, but I cannot prvent them from duplicating.

How can I use a macro on a button in SHEET 1 to generate random numbers on SHEET 2 as follows?

Cell A1: (1-10)

Cell A2: (1-6)

Cell A3: (1-100)

Cell A4: (1-12)

I've got it working with formulas, but every time I press "DELETE" the random numbers jump to new values.

I have build a system that needs a lot of random numbers generated to work.

I have used what I thought would work to generate me these numbers like this example:

VB:

Lastrow = ThisWorkbook.Sheets("RPlay").Range("A" & Rows.Count).End(xlUp).Row

RPlayerNum = Int((Lastrow - 2 + 1) * Rnd + 2)

This would generate a random number into RPlayerNum variable, based on the list in sheet RPlay, missing off row 1 as the header.

However we have noticed a massive flaw in this code.... It works as long as the excel file is open, each time run it gives a different random number. However if you close the excel file and open it, then run it, it ALWAYS gives the same number first run, every time.

I am creating an excel spread sheet for a project I am doing, I need to create a daily chart for 6 months of water usage that results in averaging set targets.

I have made a chart with the average uses per day but would like to have daily numbers that average out to what i have but in a random sequence e.g. i have that a shower uses 320 litres per day for 2 people is there a way i can make a chart that says: 300 (a1) 340(a2) 260(a3) 360(a4) etc i need to do this for 180 days with random numbers generated to average the same overall. I dont know even how to generate random numbers.

Any way to make say cells A1 thru A10 produce random numbers from 0 to 9.

I would like to do it without a macro if possible. I also need a button to generate those random numbers. I know this button may make it impossible to not use a macro. If it has to be done with a macro then so be it.

I have a process that generates the value X in cell A1 randomly. So I can change the value of X in A1 by clicking on F9. I want to sum a sequence of X values. I can do this by manually copying each X to a row of cells and then summing the row values. But that is tedious. Can the summation be done automatically without being regarded as being circuler?

I am trying to generate random numbers between 0 - 9 in ten cells that do not repeat an always include every value 0 - 9 (0, 1, 2, 3, 4,...9). The object is to have the numbers randomize each time. So cells A1:A10 could look like this:

3

9

4

5

1

0

6

8

7

2

Or, they could look like this:

9

7

5

2

8

4.................

I have two rows in a sheet with random numbers (1 till 90).

Those numbers in those two rows I change them every 5 minutes with new one still from 1 to 90

I need a "way", in one side of my sheet (lets say in column B) to count how many times a number was repeated after finish my work (example after 2 hour's)

Is that possible with excel 2007?

I want to set up a column of numbers that will be random without any repeating numbers.

Example: If I set up for 1,000 rows, I would like the random numbers to be 1 to 1,000, but the catch would be to have no duplicates in the column.

It has been several years since I worked with Excel and I am sure this can be done with a macro, but I am not sure how to go about it right now.

I'm trying to generate random numbers that will add up to a certain number and am having trouble brainstorming how to do so. For example, I'm trying to get a+b+c=6 with a, b, and c randomly generated to add up to 6.

I am using excel 2007 with XP pro.

I want to include some random numbers in a large multi-tabbed spreadsheet, but I do not want the number to recalculate every time I make another entry on the tab or elsewhere in the workbook. I would like each tab to have one or two random number options, but each should calcualte independently based on their own inputs.

The "randbetween()" function recalcs with every/any change in the workbook.

Specifically, I want to begin with a random percent between 0 and 50% and then add three fixed values (percents) and one different random percent between 0and 30%. then I want to total all of them.

Random % (0-50) + X% + Y% + Z% + random % (0-30) = total %

With a formula, how could I generate random numbers between 1 and 100 that are not divisible by 3?

I made this part of a formula that generates the numbers not divisible by 3:

MOD(ROW(INDIRECT("1:100")),3)0

But I am unsure how to use it to help to generate random numbers between 1 and 100 not divisible by 3.

I wonder if you think it can be possible to constraint the RAND function so that it gives off its result commensurate with the result of another RAND function with certain probability N? For example,

Say there are two random functions and the first generates 0,5667 the correlation is at 0,5 so there is a 50% probability that the second random function will generate the result very close to it, say, 0,6012….Do you think the second random function can be tweaked so that it performs in this manner….when there is a 100% correlation – the results of both random functions will agree…when it is 80% it will be very close…..do you think this can be done with NORMINV?

numbers between 40&50, In the Column B I will generate random numbers

between 35&45, The column C is the sum of Column A&B(i.e. C=A+B) but I

the sum should be between 83&88. I need acondition such that the random

numbers generated in Column A&B Should satisfy the Column C(A+B)

condition sdatisfying the A&B columns condition.

I have column E listing all of the favorites and column G the underdogs, each row represents one game, there are 34 all together. I want a formula to pick the team based on a random generation. That part i have....

=choose(randbetween(1,2),e7,g7)

but here is the rub.

I only want the total number of underdogs to be 20% and the favorites to be 80% of all of the picks.

I am not sure it can be done as each formula must look to what the other formulas are doing...aside from it being circular i think it just impossible or i am not as advance as some of you.

I generate a range of random numbers in column C. Then I perform another task and then copy the randoms numbers in the range c4:c(some row) into another sheet.

But the two columns are not the same? I want to copy the same random numbers into the other sheet.

Code:

'Generate random numbers

Lastrow1 = Range("c65536").End(xlUp).Row

ActiveCell.FormulaR1C1 = "=RAND()"

Range("c5:c" & Lastrow1).FormulaR1C1 = "=RAND()"

I have what seems to be a pretty complicated situation involving random numbers and letters. I need to generate random sets of this combination of 2 letters follows by 6 numbers (ex. AB123456). I need the final product to be randomly generated and non-repeated.

I have played with various methods of producing random numbers and random letters both repeated and non-repeated. The closest I can get would be a cell of randomly generated letters adjacent to a cell of randomly generated numbers which so far has been useless.

VBA or excel functions are both okay.

How to generate semi-random numbers? I have a small sample (26 points) that I would like to extrapolate out and plot on a skewed bell curve. The numbers represent a ratio which can never be less than one. The average of my sample is 1.0149 and the standard deviation is 0.01234. When I use the random number generator tool in the data analysis pack, it generates mostly good numbers, but it also produces numbers like 0.98 and such that are never possible in my data. I've made a plot with the random numbers, including the sub-one ones, and then just adjusted the x-axis so that they wouldn't show on the graph, but I know that that's not the correct way to do it. My graph isn't skewed as much as it should be.

At present I have the following formula entered and it works, but after I click F9 some repeated numbers are generated.

=INT(RAND()*(80-1)+1)

How can I change the formula or replace it?
