Question 15
In a machine, horizontal bars can tilt to the left (value 0) or to the right (value 1). When a ball falls onto a bar, it reverses that bar’s value and then falls as shown below.
Below are the changing bar states after two balls have fallen.
The sequences 0000, 0001, … represent the states of the bars at each moment. If three more balls fall one at a time, what will the state of the bars be?
