Your Marbles Or Your Life?
The Emperor approaches you and presents you with a marble game, a matter of life and death. Win the game, and you win your life; lose, and the rest is history. You have 50 white and 50 black marbles and two bowls.
The aim is to separate the marbles into each bowl, divide and mix them however you want. Then the Emperor will come and mix the marbles even more. Your aim is to pick the white marble out of your chosen bowl. If you choose a black marble, you lose the game and also your life. So how to guarantee the white marble?
