Went to summer camp today, these are some riddles that the teachers gave us :)
You are a bus driver. The bus starts out empty. 8 people get on, 2 people get off, 2 more people get on and another 1 gets off. Finally, 3 more people get on and 2 get off again. What color are the eyes of the bus driver?
You are in a windowless room with a door (closed) and three identical light switches (all of which are switched off currently). Each light switch is connected to one of three identical light bulbs outside of the room. Once you open the door, you can never touch the light switches again. How do you identify which light switch is connected to which lightbulb?
