The first prize of the famous lottery Sportka (Czech Republic) is currently about 124000 €.
Sportka allows us to select 6 numbers from 49 (array of numbers 1-49) on the lottery ticket.
I wanted to bet just for fun. So why not to generate 6 numbers by PowerShell and Get-Random ;-).
We can use for example:
PS C:\> Get-Random -InputObject (1..49) -Count 6
19
20
25
6
48
27
PS C:\> 1..49 | Get-Random -Count 6
2
22
48
20
36
9
PS C:\> 1..5 | % { (1..49 | Get-Random -Count 6) -join (",") }
35,1,37,6,31,4
7,10,47,3,37,33
28,43,44,42,21,29
31,49,7,17,14,33
30,20,2,43,29,45
And what about the following?
PS C:\> 1..6 | % { Get-Random -Minimum 1 -Maximum 50 }
48
42
45
40
30
23
It is not good idea because we can get the same numbers. It is improbable at this point but look at this:
PS C:\> 1..6 | % { Get-Random -Minimum 1 -Maximum 6 }
2
2
3
5
5
3
Of course that we can use something like that:
PS C:\> do { if( ($num=(Get-Random -Minimum 1 -Maximum 7) ) -notin $nums ){ [int[]]$nums+=$num } } while ( $nums.count -lt 6 ) $nums
3
4
1
5
6
2
But why to use that horrible command when 1..6 | Get-Random -Count 6 cannot display duplicates :-D.
By the way, the syntax does not support -Count and -Minimum or -Maximum parameters together.
- Get-Random [[-Maximum] <Object>] [-Minimum <Object>] [-SetSeed <Int32>] [<CommonParameters>]
- Get-Random [-InputObject] <Object[]> [-Count <Int32>] [-SetSeed <Int32>] [<CommonParameters>]
Feel free to use Get-Random also in the context of:
- Get-Mailbox | Get-Random
- Get-Service | Get-Random
