TED-Ed: Can you solve the multiverse rescue mission riddle? - Daniel Finkel

A team is trapped in eleven pocket dimensions due to a system bug. They have an experimental teleportation robot with two levers and a button, which can teleport randomly between dimensions. The challenge is to ensure everyone pulls a lever before pressing the button to return home. Communication is limited once the robot arrives, so a plan is devised where one person counts visits using the left lever. Once all have been visited, the button is pressed to bring everyone back. The plan is successful, though it may take many teleportations.

What must each team member do when the robot appears?

What is the final outcome of the mission after the robot completes its teleportations?
