A drawer contains n white and n black socks. Each white sock has a unique design, and each black sock has a unique design. Two socks are selected at random from the drawer. Every way of selecting the two socks is equally likely, and the order in which the socks are selected does not matter.
A) How many ways are there to select the two socks?
B) How many ways of selecting the socks result in two socks of the same color being chosen?
C) What is the probability that a randomly chosen pair of socks are the same color? Simplify your final expression as much as possible so that it does not include any expressions of the form (a/b).
