24 socks (8 pairs of black and 4 pairs of brown) are in a jumble on the closet floor. If you reach into the dark closet (the light fixture is broken), the only thing you can tell about one of the articles from the jumble is that it is a sock. How many socks must you get from the pile to be sure that you have a matching pair of socks?

If the same puzzle referred to gloves instead of socks, how many gloves would you need to get to be sure of a matching pair?
