A box contains 3 red balls and 3 blue balls. You draw one ball at random. If it is red, you remove it and do not replace it, then draw a second ball. If it is blue, you return it to the box along with one additional blue ball, then draw a second ball. What is the probability that the second ball drawn is red?
