Decision Support Puzzles for Applied Mathematicians
The building I work in has three elevators and twelve floors. Like some elevators, these have displays above them that indicate the current floor that the elevator is on and also the travel direction of the elevator.
The travel direction display can show Up, Down, or Stopped indicated by an up arrow, a down arrow, or a dash character respectively. As an example, Elevator A in the image is on the 2nd floor and is traveling in the up direction.
Below are 10 historic data points showing the floor and direction of the elevators from times that I have used the elevator in the past. The table also shows which elevator showed up first on the ground floor.
Question: For scenario #11, which elevator is most likely to be first to the ground floor?
