You have 10 pairs of socks, 5 black pairs and 5 blue pairs, but they are not paired up. Instead, they are all mixed up in a drawer. Its early in the morning and you don't want to turn on the lights in your dark room.
1) How many socks must you pull out to garantee that you have a pair of one color?
2) How many must you pull out to have two good pairs (Each pair is the same color)?
The answer for 1) is 3 and for 2) its 5.
Why isn't 2 for 1) and 4 for 2) instead?
