All "draw-style" games can be simulated in the same way. They rely on
drawing without replacement. Say the rules for a lottery are there are 50
balls numbered 1 thru 50. Five balls are drawn at random.
In A1 thru A50, enter 1 thru 50.
In B1 thru B50, enter =RAND()
Sort cols A & B by column B. This will "shuffle" the values in column A.
Use the first 5 (A1 thru A5)
For another draw, just repeat the sort.
Change the ball numbers and number of balls drawn to match your particular
lottery.
