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?

Are there five pairs or five socks

If there are five pairs, I need to pull out atleast six socks (not pairs)
