The answer is 5 socks. There are only 4 different colored socks, so you could only grab a maximum of 4 socks before you would double up on colors. If you wanted to guarantee you had 2 of the same colored sock then you would need to grab 5 socks. wateva

A slim, modern lampshade in black or egg white will go great with a black dresser.

Open the drawer. On the inside on both sides is a screw with a corresponding nut on the outside of the drawer holding the rail to the drawer. Remove these two screws and the rails will slide out of the drawer. When replacing the drawer make sure the rails slide into the slots on the drawer.

You can find a black dresser at any furniture store. You could also check craigslist, and Ikea typically has cheap furniture if you're willing to put it together.

I assume you mean a matching pair. If so, the answer is 13.Considering the worst-case scenario, she may pick all six left-handed brown gloves and then all six left-handed black gloves. In which case, the next glove would definitely be a right-handed (black or brown) glove giving a matching pair.Even in complete darkness, Cathy might be able to discern the difference between a right and left-handed glove (mittens not so much). So, as written, the answer is two. If we assume a matching pair, the answer is eight.
