Lottery/Slot Machine Triggers

I need a tutorial on how to make triggers that have the lottery in them:
For example, i need the triggers to have odds such as for my slot machines.
and for the lottery, i need like numbers so that their tickets have numbers (like if they type "-ticket" they see their numbers) and the numbers are drawn at six and it gives off numbers, and if they get it they win.

I would greatly appreciate this.

I cant give you the specific, but it will most likely come in the form of:

Event:
Player one types -whatever
Condition:
Action:
Set 'variable' to a random number betwen 1 and 10.
If 'variable' is equal to or less than 7 (70%) then do whatever.
If 'variable' is equal 8 or 9 (20%) then do whatever.
If 'variable' is equal to or greater than 10 (10%) then do whatever.

Sorry I couldn't paste an actual trigger, but this should get you going in the right direction. The next guy that posts will probably have a more elegant solution. (i hope)

thanks, but i still need the lottery one

You should experiment, don't have someone make your map for you. Try and figure out how to do it yourself.

The lottery one would be very similar. Easier in fact.

Event:
Player one types -whatever
Condition:
Action:
Set 'variable' to a random number betwen 1 and 1000.
If 'variable' is equal to 437 then do whatever, else do nothing.
