The damn things are already brighter than me .:( I couldn't work out this puzzle .

a fictional king is choosing a new advisor and gathers the three wisest people in the land. He promises the contest will be fair, then puts either a blue or white hat on each of their heads and tells them all that the first person to stand up and correctly deduce the colour of their own hat will become his new advisor. :wink2:

Suppose that there was one blue hat. The person with that hat would see two white hats, and since the king specified that there is at least one blue hat, that wise man would immediately know the color of his hat. However, the other two would see one blue and one white hat and would not be able to immediately infer any information from their observations. Therefore, this scenario would violate the king's specification that the contest would be fair to each. So there must be at least two blue hats.
Suppose then that there were two blue hats. Each wise man with a blue hat would see one blue and one white hat. Supposing that they have already realized that there cannot be only one (using the previous scenario), they would know that there must be at least two blue hats and therefore, would immediately know that they each were wearing a blue hat. However, the man with the white hat would see two blue hats and would not be able to immediately infer any information from his observations. This scenario, then, would also violate the specification that the contest would be fair to each. So there must be three blue hats.

Since there must be three blue hats, the first man to figure that out will stand up and say blue.

Edit- I didn't know this but found it on the internet.

It used to be easy for me to figure this stuff out once upon a time. :(

Thanks for the explanation DaveO How did you like the little robots ? if I had a spare £5k I'd buy one for sure.:laugh:
 
Thriller amazing synchronised dancing :wtf:
 
I'm just blown away by the advances in robotic technology .

Many years ago my Company specialised in Animatronic interactives for Theme parks, Museums and Visitor centres. My animatronic heads now look positively Stone age in comparison.:laugh:
