How do I script a random chance of winning?

[Guest Messenjah]

So, in Skyrim it is pretty simple. I'm just not sure how it works in Fallout:NV.

 

What I need to do, is I need to write a script where the player can "win" a simple mini-game if he pays 5 caps to an activator. So, I need the game to select a random number between say 1 and 20 (Thus the player has a 5% chance of winning), and if the number is, lets say 11, they will get a win. Or, if we go 1-99, I could pick 5 random numbers that the player can win with as well if we want to get a bit more complicated.

 

It doesn't really need to be very complex for what I'm doing. Just something very simple.

The function GetRandomPercent will generate an integer between 0-99.

 

So, to get a 5% chance, use:

if GetRandomPercent < 5

Or:

if GetRandomPercent > 94
