### The Missing Dollar Puzzle:

• Three friends check into a hotel room that costs \$30. They each contribute \$10, handing \$30 to the hotel clerk. Later, the clerk realized that there was a special rate for the room, and it should have only been \$25. The clerk gives \$5 to the bellboy and asks him to return it to the three friends. However, the bellboy decides to keep \$2 for himself and gives \$1 back to each of the three friends. Now, each friend has paid \$9 (a total of \$27), and the bellboy has \$2, making a total of \$29. What happened to the missing dollar?

### The Four 4’s Puzzle:

• Using four 4’s and any mathematical operations you like, can you represent each of the numbers from 1 to 100?

### The Bridge and Torch Problem:

• Four people need to cross a bridge at night. They have only one torch, and the bridge can only hold two people at a time. The four people walk at different speeds: one can cross the bridge in 1 minute, another in 2 minutes, another in 5 minutes, and the slowest in 10 minutes. When two people cross the bridge together, they must go at the slower person’s pace. What is the shortest time in which all four people can safely cross the bridge?

### The Monty Hall Problem:

• You’re on a game show and presented with three doors. Behind one of them is a car, and behind the other two are goats. You choose a door, and the host, who knows what’s behind all the doors, opens another door revealing a goat. You are then given the opportunity to switch your choice. What should you do to maximize your chances of winning the car?

### The 100 Prisoners and a Light Bulb Puzzle:

• There are 100 prisoners in solitary cells. There’s a room with one light bulb that is initially off. Each day, one prisoner is taken into the room. They can either switch the bulb on or off, but they cannot communicate with each other. The prisoners can stop this process at any time, and if they can prove that all 100 of them have been in the room, they will be set free. How can they do it?

### The Elevator Weight Riddle:

• You have a 13-story building with one high-speed elevator. The elevator has a weight limit of 1,600 pounds. Four people enter the elevator on the ground floor, and each person has a different weight: 150 pounds, 200 pounds, 250 pounds, and 400 pounds. If the elevator makes no unscheduled stops, how can you determine which floor each person got off on, using the weight display and the floors passed on the way up?

### The 3 Ants on a Triangle Puzzle:

• Three ants are sitting at the three corners of an equilateral triangle. Each ant starts moving along a side of the triangle. What is the probability that they do not collide?

### The Chessboard and the Dominos Puzzle:

### The Two Jug Problem:

• You have two jugs, one that can hold 3 gallons of water and another that can hold 5 gallons of water. You also have access to a water source. How can you measure exactly 4 gallons of water using only these two jugs?

### The Rope and Burning Matches Puzzle:

• You have a rope that takes one hour to burn from end to end. You also have two identical matches, and each match takes 30 minutes to burn completely. How can you measure 45 minutes using these materials?
