I have a set of data with index numbers and the percentage of their occurrence. I want to use this percentage to weight the occurrence of the index numbers and create a random list of say 500 occurrences.
Index %
1 7.95
2 3.28
3 7.37
4 38.45
5 28.62
6 14.12
This is kind of an extension to a previously solved post. For a similar problem I used the attatched file (which someone from here so kindly came up with - but to be honest i dont fully understand),
but now im getting onto numbers from 1 to 100 so could get very confusing in the table!
RANDOM TABLE2.xlsx
Basically I want to produced a random number, (which I have managed) then another number, but it cant have any common factors as the first.
So 1st = 10, 2nd = 13 is acceptable
but 1st = 22, 2nd = 12 is not.
I have managed to do it with smaller values by just typing then out, but this is a very long winded technique, but is there a formula that can do this?
I have a range of cells that have values from 1 to 7 in them. What I would like to do is to have the next column generate a random number from 1 to 7 that does not generate the number that the cell next to it has. for example if cell A1 has 6 in it, I would like cell b1 to generate a random number other than 6 in it. if cell A2 has 3 in it then cell B2 would generate a number other that 3 (1,2,4,5,6, and 7).

I have 4 names, and a grid of 100 boxes. I need those 4 names randomly deposited in the 100 boxes, making sure each name is displayed an equal number of times (25 each) Is there an Excel formula to compute this?
View 9 Replies View RelatedWhat I'm trying to do is as follows:
Sheet 1
A1 through A6 has STR, DEX, CON, INT, WIS and CHA. B1 through B6 is waiting for results from sheet 2.
Sheet 2
A1 is data validation of d4, d6, d8, d10, d12, d20 and d100. A2 through A7 are currently Rand formulae triggered by A1 with B1 adding number of dice (minimum 1) and B2 a modifier value add to the rolled result. D2 through D7 are data validation modifiers of -10 to +10 (0 included). E2 through E7 is the result of A2+C2. The Rand works fine, but every time data is changed Rand recalculates. I'm hoping for a macro executed by a button to generate six random numbers based on the chosen die value of A1 ranging from 1-4 to 1-100. The die roll can never be below 1 and no higher than the chosen die. I then want to transfer the result from E? To sheet 1 B1 to B6 matching its appropriate atribute. I named them Char01_STR, etc on sheet 1 A1 to A6.
I have code that generates random numbers 1 - 90, what I would like is when the command button is pressed the numbers are generated every 5 seconds, I have attached the workbook.
View 5 Replies View Relatedhow to go about generating random numbers based on Weibull distribution in VBA? I had a rough idea for Normal (from link below) which i later extended to Lognormal but am having difficulty with Weibull and Gamma will appreciate any help.
http://www.devx.com/vb2themax/Tip/19233
I would like to get random number generator for normal distribution and I’m using:
=NORMINV(RAND(),$B$1,$B$2)
Where B1 is mean (average) and B2 is SD.
This command works, but in the random generating numbers, I’m getting positive and negative numbers (ex. -23,34).
how to change command so I can generate positive only numbers?
As you can see below, I've written code that writes random numbers into three columns of a spreadsheet (10 numbers in each column).
What I want to do is create code that will run the random number generator for a period of 1 minute and then stop. I know that I will need to write a timer subroutine to do this but I'm how unsure how to do this.

View 3 Replies View RelatedI am organizing a sports tournament and would like excel to randomly generate the teams for it.
We have 20 people who will be organized into 10 teams of two. how to setup the formula to have two people randomly paired together without duplication. The names will be further used in other formulas for points calculations.
So, I have the names as A1:A20 and then would like the teams generated from B1:B10 and C1:C10 with the team being the row and the team members in the B and C columns.
I am trying to create a random name generator. I have tried something like this...
=INDEX('TM Names'!$A$2:$A$36,INT(RAND()*35+1))
But sometimes it will give you the same name 2 or 3 times in a row. I need it to pull up a different name each time, from a list of names I already have.
In Column A I have a list of 8 team names.
In column AB I have a list of 28 weeks written in date format.
In column B I'd like to chose one week from the 28 weeks listed in AB at random. But B2 - B9 can not have the same date (ie could not have two dates for the 19th of April).
How exactly is that done?
Alternatively - is it possible to have in Column AA the 8 team names. In Column AB the 28 weeks. In Column A a random team picked from column AA and in Column B a random date picked from Column AB. Both column A and Column B can not have duplicates... There's 28 weeks with 8 teams - therefore I only need 8 unique weeks.
Has anyone seen an Excel program that will generate words based on letters entered. For example, if I had 10 cells in a row, and each cell contained a letter (duplicates are okay), what words could be derived from arranging those letters in random sequences.
It would need the ability to accept any letter of the alphabet, A thru Z
E A L R C T S S U C
___ ___ ___ ___ ___ ___ ___ ___ ___ ___
How many words could it generate, and what are the words?
I assume it would have to reference a spelling dictionary.
It could be used as a spelling learning game, etc.
I like to know if this can be done using vb.
If I have a list of names of associates B2 to B32. Can I randomize the list in any order.
Then if I need to want that list to only randomize B2 to thru B30

And so forth.
Sort of being able to pick from a pop up message box or userform that will ask you how many names to randomize in that list.
I wrote this to help me generate a random password for a workbook. I am happy with it so far, but I was wondering if there is a way, to shuffle the order of the variables? So, instead of MyPassword always being A, B, C, D, E etc

Dim A As String, B As String, C As String
Dim D As String, E As String, F As String
Dim H As String, I As String, J As String
Dim K As String, L As String, M As String
Dim MyPassword As String

A = Chr(Int((UBound(v) - LBound(v) + 1) * Rnd + LBound(v)))..............

I need a formula to create random letters down a column: A-F. Probability of A=3%, B=6%, C=8%, D=11%, E=14%, F=16%. I've got it worked out to where each letter is a header of a column ("A" is in A1, "B" is in B1, etc.). My question is: how do I consolidate that in one column, so that, "A" for example, reads ABFCBACFBFBECEABCEABCEAFBCEFBCAFEBCFAEBFC...? I'm using the random number generator for the 6 columns...thx

I could even shorten it a bit by placing like this. MATCH(SMALL($A$2:$A$4,B2),$A$2:$A$4,0). Of course this is only the start and it would have in column B 1-50 and in column C&D 1-35 for the selection process. Then I was going to set up on sheet 2 my list of questions 1-50 and my idea was to use 1.1, 1.2, 1.3, & 1.4 for the answers to question 1 and then vlookup. so that when and if question 1 is part of the 35 random then I could pull the answers over as well. but as I started the 'animal' will get bigger and bigger fast.
