I have three columns A,B&C In the column A Iwill generate random
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.
The code below generates numbers in the range (A2: H2)

I get the following error whenever I try running a Monte Carlo simulation with iterations in excess of 64000 (The MC simulation calls the 'NormSInv' worksheet function at least once per iteration, and the argument to the 'NormSInv' function is always a standard normal RANDOM number also generated by Excel VBA): Run-time error '1004': Unable to get the NormSInv property of the WorksheetFunction class
Why do I inevitably encounter this error ONLY when the number of iterations exceeds 64000, for instance? Simulations with iterations < 64000 run smoothly without a glitch.
I understand how RAND and RANDBETWEEN work, but have a slightly more complicated random number generation problem that requires a number that isn't solely between two numbers.
I have one cell that is randomly generating a number between 0 and 350 (we'll call this value A) and another randomly generating a number between 0 and 15 (value B). Then, I have a third cell (value C) that equals 15 minus B. Where I am having trouble is with a fourth cell (value D). This cell I want to have randomly generate a number between 0 and 350 but it needs to be D less than the value in A or C more than the value in A. Is there an advanced random number generation technique that can solve this?
Been trying to think of a way to get random numbers 1 to 36 generated without repeating in the same column, however also getting it to perform the same opertaion in 9 more columns (B:J) without the same number appearing in the same row.
example
1 2 5 4
2 5 3 1
3 4 1 5
4 1 2 3
5 3 4 2
Unsure if this is possible, have created a basic script for random number generation but have no clue how to expand across columns.
it is possible to generate a completely random number generation in excel?
Other than using the rand() function and then sorting by top or bottom (as then have affected the sample by choosing which direction it is sorted).
And the randbetween() function changes everytime you modify a cell.
I would like to generate a random value using a skewed normal distribution. For inputs I have the sample mean, standard deviation, and skewness. I would like to find a way to generate numbers randomly that would fit the skewed normal distribution described by the inputs.
Some information about skewed normal distributions can be found here: ...

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 had some difficulty searching this on the web, but how would I generate a random number between 1 and n?
View 9 Replies View RelatedI 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?
View 8 Replies View RelatedI 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

1
0
6
8

Or, they could look like this:

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 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 %
