This is a riddle: It is night time in your bedroom and the light has broken. You are getting dressed and need a pair of socks. You have got 10 red, 8 white and 12 grey socks in a drawer how many do you have to pull out in the dark before you know you have a matching pair?

Four will ensure you've extracted at least two of the same color  but unless you turn the light on there's still no guarantee that you'll get two of the same color on you feet. Is that why it's a riddle?
