16 choics total, take out all with a cactus or clay pot
Plant 1 Plastic
Plant 1 Metal

Plant 2 Plastic
Plant 2 Metal

Plant 3 Plastic
Plant 3 Metal
Plant 3 Wood
9 choices left, so probability is 9/16
to do it for any number find the total number of choices again, so 16 then you subtract the number of each category you are excluding. so there were 4 cacti and 4 clay, so subtract 8, to get 8. Then you add back any that had both clay and cacti, which there was one, whn you had a cactus in a clay pot, so add back 1. This gets us 9 again.
This is called the inclusion exclusion principle. Might want to look into this specifically.
