independent

Step-by-step explanation:

I usually like to begin with counting the denominator possibilities, for often that is the easier concept to count (the sample space; all possible outcomes). Here the denominator or count of the sample space is to count all of the ways that we can pull two socks out of the drawer. When I pick a pair of socks I don’t care about the order of the draw, I simply want a subset of size two, so combinations is the way to go. That is I see this mathematically as counting all of the subsets of size two that are possible from a set with 12 elements. Now in the numerator we only want to count those match-ups that are actual pairs of socks. So I thought about this as a sequence of picks where the first draw may be from any of six pairs followed by only one choice for the second draw, for it must match the pair that I drew from.
