You face two doors. One leads to freedom, the other to a deadly trap. Two guards stand in front, one always tells the truth, the other always lies. You can ask one question to figure out which door to take. What do you ask?
Focus on what both would say about the same door.
Ask either guard: “If I asked the other guard which door leads to freedom, what would they say?” Then pick the opposite door.
23. The Light Switches
You are in a room with three light switches. In another room, there are three light bulbs, each controlled by one switch. You can only enter the room with the bulbs once. How can you figure out which switch controls which bulb?
Heat is your friend.
Turn on the first switch for a while, then turn it off. Turn on the second switch and leave the third off. Enter the room: the bulb that’s warm but off = first switch, the bulb that’s on = second switch, the cold bulb = third switch.

The water level in a reservoir is low but doubles every day. It takes 60 days to fill the reservoir. How long does it take for the reservoir to become half-full?
It’s not 30. Try to think backwards. If it was full on day 60, how full was it the day before?

Your friend flips two coins behind your back and tells you, “At least one of the coins came up tails.” What is the probability that both coins came up tails?
Think of all the possible outcomes for two coins. Then think of the possible outcomes, given your friend’s statement.
⅓. There are four possible outcomes when you flip two coins: HH, HT, TH, and TT. Because at least one of them is tails, that leaves you with only three possible outcomes. Out of these three, only one is TT. Thus, the probability is 1/3.
11. Ancient Coins
