Debbie and Scott are responsible for washing the dinner dishes. They decide to use a random method to select whose turn it is. They put some red and blue tiles in a container. Without looking, each draws one tile. If they match, Debbie washes. If they are different colors, Scott washes.

How many of each color tile could be in the container to make this method "fair"?
What other solutions can you find?

how about two tiles of each color?

not fair, since there is only a 1/3 chance of matching colors.

What other amounts have you considered?
