Maria needs to mail 3 letters. each letter costs $0.41 to mail. how much change will she get back if she gives the clerk $2.00?

1. I would think it would be a appropriate to use a normal model to figure this out because sometimes when you are using stuff online you can get the same number like 20 times in a row, whereas, if you use a real dice, you most likely won't roll the same number 20 times.

2. { sorry two doesn't make sense }
