You have 10 pairs of socks, five black and five blue, but they are not paired up. instead they are all mixed up in a drawer. it is early in the morning and you do not want to turn on the light.

1. how many socks must you pull out to guarantee 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)?
