1. Harry Potter is trapped in the Department of Mysteries. Three doors lead out from the centre room, one returning back to the centre after 2 minutes, one returning back to the centre after 4 minutes, and one leading to his goal (the Hall of Prophecies) after 10 minutes. Unfortunately, every time he enters the centre room, the doors randomly spin around so he cannot remember which doors have been tried already, so he chooses randomly. [3]
