A chimp is being trained in the laboratory to replace the circuit breaker and other tasks for the Mars mission. To prepare the chimp for extreme cases, the instructor gives her 100 circuit breakers in a chamber that contains 100 different bulbs. The controller is outside the room. All the bulbs are on. Chimps should install circuit breakers one by one and check inside the chamber whether a bulb is off. If the trainers were training chimps to be the most efficient as they were, what is the minimum number of trips they would expect to make?
