A box contains 24 tiles. Each tile has certain properties:

Each tile is made of wood or plastic.

Each tile is red, yellow, or blue.

Each tile is a triangle, square, pentagon, or circle.

There is exactly one tile for each combination of properties. For example, there is one red circle that is made of wood.

Steve chooses one tile, and Ellen chooses a different tile. What is the probability that the two chosen tiles have exactly two properties in common?
