- With regard to the three guys standing in line with 5 hats available: 3 brown
- and 2 black. The first guy in line has a brown hat. Because:
-
- The last guy does not see 2 black hats or he would leave knowing he has a
- brown hat.
-
- The middle guy does not see a black hat or he would leave knowing he has a
- brown hat.
-
- So the first guy knows he has a brown hat.
