combination of 5 numbers from the 90 numbers with,at lease 2 numbers combined together (for

instance-1 22, 30 57, 42 90) till the 90 numbers are covered in 100-150 tickets.
Please do this for me.

Regards

I would be grateful if you can help me out to I generate these numbers on excel or other software.

I will apply these random numbers to simulate the rainfall in one month having known the sum of rainfall during that month.

I think my posting on Sep 24th covers this. Did you have a question about my explanation?

how can i generate a list of random numbers based on the data shown as above?

thanks and regards

My post of July 10, 2011 is mostly about non-repeating random numbers, but part of it is about controlling when random numbers are generated. It involves using the iterative/circular reference capability of Excel. If you set the below cells to the values that I indicate, you will see how this works in small scale.

A1 Y
A2 =If(A1=”Y”,Rand(),A2)

As I say above, you will have to set up Excel to do circular reference. Then press F9. Every time you press F9, it will give you a different random number in cell A2. Now, put N (or actually any character other than Y) in cell A1. Now press F9 as many times as you like and the random number in A2 will remain the same.

If you always ensure that cell A1 is not Y before you save it, then you will start with the same random number as you saved it with. You can then choose when to set A1 to Y and get a new random number. Hope this helps.

(In my previous posting above I used this trick when generating a series of non-repeating random numbers so I could lock them down until I wanted to generate a new set. My idea was that you could use this to to generate a random series that you could use to do something like dealing 52 cards or selecting randomly which units out of the max number of units would fail.)

I can’t seem to figure out if I am able to upload a file showing how, so below is a description of the process. If Maria wants to post the file, she can contact me.

A1 contains “Recalculate?” B1 contains n (to start with, Y when you want new random numbers)
A2 =IF(B1=”Y”,TRUE,FALSE)

The range A5:A104 contains the numbers 1 through 100

Put the formula =IF(A5>C$4,”",IF($A$2,RAND(),B5))
into cell B5, then drag this down to row 104.

The last IF part of this formula sets up a circular reference that allows you to lock the random numbers. You will need to set your Iterations to at least 1. In Excel 2003, you get to this via Tools\Options\Calculation\Iteration. If you have another version and don’t know how, search the help for “iterations” and it should tell you.

Cell C4 will contain the upper limit of the of random numbers that you need, that is, if you want non-repeating random numbers from 1 to 64, this cell should contain 64.

Put the formula =IF(B5=”",”",RANK(B5,B$5:B$104,1))
in cell C5, then drag this down to row 104.

Put the upper limit number in cell C4, put Y in B1, and you will get non-repeating, but random selection, of the numbers between 1 and your upper limit. If you want to lock these numbers down, then enter N in B1. If you want to see more random sequences, then press F9.

The upper limit in my example can’t be more than 100. However, you can expand this by dragging the cells A104, B104, and C104 down to as large as you want, up to the limits that Excel imposes. Hope this helps.

I will try it soon.

Best regards from Mauritius.

replace the two text strings with the proper symbol. Yes means between the numbers 95 and 125 and No means it isn’t.

Not sure if this will be better than what I posted before, hope so.

In this example D8 is the cell with the total of the 6 random numbers in it prsumably located at D1-D6. Trying to get the NO answers to delete the D column but no luck so far.

Today, I am trying to get it to generate 6 numbers from 1 to 40 for the loto. No problem to get it to general 6 numbers between 1 and 40 in 6 cells. =randbetween(1,40) No problem to sum up the 6 random number. =sum(f1:f6) BUT, BUT, the big problem is to get it to generate a list of the sums from 95 to 155 (for example). I am looking for a formula to generate all sets of 6 numbers between 1 and 40, and them to show all the sets of 6 numbers between 95 and 155. Can Somebody help, please ?
