aaaand the question for today is:
Q. You are to divide 9 balls - 4 green and 5 red into 2 boxes. You pick a box at random and a ball from it at random. If it is red, you DIEEEE!, if it is green (I will let) you live. How would you maximize your odds of living?
Q. An emperor wants to find the cleverest of all men in his country to appoint him as his minister. There were three who made it to the last. The emperor places a crown on each of their heads, such that each man could see all of the other crowns, but none their own. Each crown was either gold or silver. The emperor gave his word to the wise men that at least one of them was wearing a gold crown; and that the contest would be fair to all three men. They were also not allowed to speak to each other. The emperor declared that whoever stood up and correctly announced the color of his own crown first would become his new minister. The men sat for a very long time before one stood up and correctly announced the answer. What did he say, and how did he figure it out?
