In a certain sock drawer, there are 5 white and 4 black unmatched socks.  You reach in and pick 2 socks at random (without replacement).   What is the probability that they are different color (one white and one black)?  Write your answer as a decimal rounded to 3 decimal places.  (Hint: if you haven't already, it might be a good idea to make a probability tree for this problem.)
