For my online Statistics and Probability class, I have to create a very simple lottery scratch off game. I have to design a scratch-off lottery ticket. Can any1 give me an example for a ticket design that works with the below criteria? Thanks, any help is very appreciated.

> Ticket will sell for $1.
> Have a prize no more than $100.
> Their can be no more than two prize levels.
> Lottery will print 100,000 tickets. Half are expected to be sold.
> Lottery is making $25,000 in prize money.
> The lottery want's to make a profit of $30,000.
