A King, Three Prisoners and Five Hats
June 22, 2009: Welcome! According to the info I get from Statcounter, this entry is the most popular one on my blog. Seems like everybody, all around the globe, is searching for the answer to this question about hats and kings and incarcerated folks. Interesting question.
While I've got you here, I would like to let you know about Boomerang, my recently released novel. You can read the first chapters right here on my blog and of course it is available through Amazon, Barnes and Noble and all those other places that sell books. Not a lot of hats, and no kings, but it's a comic novel of international intrigue and those who have read it love it!

And now, the hat entry that brought you here in the first place!
Our son is in his final year of college, on his way to becoming a teacher. Yesterday he came home with a problem his "How To Teach Math" professor had given his class as an example of a long term problem they could give their students to ponder. According to this professor, this question usually takes most people quite a while to solve. Our son said he got the answer in less than a minute.
A king has three prisoners brought before him. He has their eyes covered and a hat placed on each of their heads. Then he has the eye coverings removed. He tells them,
"I have five hats, three black and two white. Three of those hats have been placed on your heads. If you can tell me which color hat is on your own head I will set you free. If you say wrong, however, you will be put to death. You may look at your fellow prisoners to see what they are wearing, but of course may not look at the hat on your own head."
The first prisoner looks at the other two, ponders as best as he can, and finally says,"I have no idea."
The second prisoner looks at numbers one and three and shakes his head, discouraged. "Heck if I know."
The third prisoner, who is blind, says, with nary a bit of hesitation. "I am wearing a black hat."
The king says, "Correctomundo! Off you go." And sets the fellow free after first restoring his cane and seeing-eye iguana and pointing him in the direction of the nearest Tastee-Freeze.
The question is: Did the blind man know or guess? And if he knew, how did he know?
My first response was that the blind man had a monkey on his shoulder who tapped out the answer in Morse Code. This did not satisfy my son.
My next answer was that the blind man was so despondent over his condition and the fact that the prison had no soft serve ice cream that he did not care if he guessed right or wrong and simply lucked into the right answer. My son tells me I am mistaken and the ice cream reference was inserted by me without his permission.
Any answers out there?
