Puzzling Socks


Here is a puzzle about socks;

You have a drawer in your bedroom that contains an assortment of black, blue and brown socks. You start randomly taking individual socks out of the drawer, but it’s too dark to see what colour socks you have taken. How many socks do you need to take out in order to guarantee that you have got a matching pair?

The answer is Four socks. Taking out one more than the number of colours of sock in the drawer guarantees at least one pair.


Unfortunately this doesn’t help me. Each of my socks have one matching sock, so to find a pair I have to remove almost all of them.
