I think this is a pretty easy one.

You have 13 people in a room. at least how many of them have their birthday is the same month?

Sorry... simple things for simple minds. :S

You are in a room with three light switches, each of which controls one of three light bulbs in the next room. Your task is to determine which switch controls which bulb. All lights are off. Your constraints are: you may flick only two switches and you may enter the room with the light bulbs only once. How would you set about determining which switch controls which bulb?



I didn't see a reply to this yet so (sorry if this is a repeat).

Flick on 2 switches, and after 2 minutes, flick ONE of them off again.

Then go into the next room. One light will be on (the switch that is still on), one will be off and cold (the switch you didn't flick), and one will be off but warm (the one you left on for two minutes).

The only sure way to survive a canopy collision is not to have one.
