Puzzle - Answer

I have a drawer full of socks. There are 5 socks of each colour, red and green, evenly mixed. In the morning, when it is very dark, I need to pull out a pair of socks of the same colour. How many must I pull out of the drawer to ensure that I have at least one pair of matching socks?

Answer: Three socks.

Once we have 2 socks, then any other will form a pair.
