In a dark room, 3 blue hats and 2 green hats sit on a table. 3 people, 1 blind, enter the room. Each of the 3 people takes a hat random, without being able to see what colour they wear. The remaining 2 hats are taken out of the room.
The light is switched on and each person is asked to say whether they can guess the colour of the hat they are wearing.
