A drawer contains 8 red socks, 4 white socks, and 2 blue socks. Without looking, you draw out a sock,
return it, and draw out a second sock. What is the probability that the first sock is white and the second
sock is blue?

prob(white, then blue) , sock is returned after draw
= (4/14)(2/14)
= 2/49

if the first sock in not returned it would be
(4/14)(2/13) , just thought I would include that thought.
