Chapter 59 Socks and Gloves

In one drawer were ten pairs of white socks and ten pairs of patterned socks, and in the other drawer were ten pairs of white gloves and ten pairs of patterned gloves.Now choose a pair of socks of the same color and a pair of gloves of the same color.

Question: How many socks and gloves do you need to take from each drawer if you close your eyes and pick them up?
[Answer: Just take three socks, since at least two of them are the same color.

The way to get the gloves is a little more troublesome, because the gloves not only have color problems, but also have left and right problems.At least 21 gloves must be taken out to make a pair that meets the requirements of the question.If it is less than this number, even if 20 of them are taken out, it is possible that all 20 of them have the same side.For example, 10 white gloves and 10 floral gloves are left-handed. ]
