Santa has lots of mixed up socks in his sack if he has 6 green socks 4 gold socks 8 black socks and 2 red socks what is the minimum he needs to pull out of his sack to get a matching pair
There are four (4) different colors of socks in his sack.
So, even if he's in a dark room and does it all without looking, he will absolutely positively definitely have at least 1 matching pair in has hand after he pulls out 5 socks.
The first 4 could have all been different colors. But the 5th sock MUST match one of the other four.
