A certain ski shop sells pairs of gloves in 11 different colors. If one pair of each color is dropped in a bag and a store clerk reaches in to draw two individual gloves simultaneously and at random, what is the probability that she draws two gloves of the same color?
Select the correct option: A) 1/144 B) 1/143 C) 1/21 D) 1/23 E) 1/12
