There are 2 different colors of socks in a drawer.
Without being able to see inside the drawer, how many socks must you remove from
the drawer to ensure that you will have a pair that match?
3 socks.....the 1st sock you
take could be blue or black, the 2nd
sock you take could also be blue or
black. This means you may have 1
of each color, but on the 3rd try you
must make a pair match with either
color.
