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 Steve's tile is wood or yellow, and that Ellen's tile is triangle or blue?

The probability is 3/8.
