I have a drawer which contains 40 socks in the following numbers and colors: 12 tan, 9 brown, 11 gray, and 8 blue. Suppose I am blindfolded. What is the fewest number of socks I must pick from the drawer to be absolutely certain that I have two socks of the same color among those I have picked?

  2. If you draw 4 socks, you could get one of each color. The fifth sock has to match at least one of the socks that you drew.

    If you have trouble visualizing this, try it with socks, or playing cards, or colored paper, or M & Ms.
