Randomly selected numbers

Hi
How can I randomly select six different numbers at any one time i.e lottery
numbers. I have tried using the formula
=INT(RAND()*49)+1, which works OK but I get repeated numbers, can anyone
help?
Keith

Keith,

Here is what I use for the California lottery to
pick 5 non duplicate numbers from 47 possible...

'-------------------------------------------
Dim i As Long
Dim j As Long
Dim ArrTwo(1 To 47) As Long
Dim ArrOne(1 To 5, 1 To 1) As Long

Do While j < 6
Randomize (Right(Timer, 2) * j)
'Int((upperbound - lowerbound + 1) * Rnd + lowerbound)
i = Int(Rnd * 47 + 1)
If ArrTwo(i) <> 99 Then
ArrOne(j, 1) = i
ArrTwo(i) = 99
j = j + 1
End If
Loop
'-------------------------------------------

Hi

The usual way to do this is to fill down 49 cells with the numbers 1 - 49
and then in the next column fill down
=RAND()
and then sort on the second column. You can then select the top 6 numbers.
Each time you sort on the column, the RAND will refresh and give you a
different list.

Since you say this is for a lottery, I guess you'll be using it quite often.

This procedure will allow you to display a new set of numbers each time you
hit the <F9> key.

First, you have to enter the RAND() function in a column, and then refer to
that column with a formula.

Say you use Column Z.
Enter
=RAND()
in Z1, and copy down to Z49.

Then, place this formula anywhere, and copy it down as many rows as you wish
to display your random numbers:

=INDEX(ROW(A1:A49),RANK(Z1,Z1:Z49),Z1:Z49)

Now, every time you hit the <F9> (calculate) key, you'll get a new random
display.

It will really work better if all the numbers are included when you copy
down the formula.

Forgot to anchor the references with absolutes.

Use this:

=INDEX(ROW($A$1:$A$49),RANK(Z1,$Z$1:$Z$49),$Z$1:$Z$49)

Take a look here:

Usage:

Select 6 cells and array-enter:

=RandInt(1,49)
