The 100 Seat Airplane
People are waiting in line to board a 100-seat airplane. Steve is the first person in the line. He gets on the plane but suddenly can't remember what his seat number is, so he picks a seat at random. After that, each person who gets on the plane sits in their assigned seat if it's available, otherwise they will choose an open seat at random to sit in.
The flight is full and you are last in line. What is the probability that you get to sit in your assigned seat?
The flight is full and you are last in line. What is the probability that you get to sit in your assigned seat?
Hint: You don't need to use complex math to solve this riddle. Consider these two questions:
What happens if somebody sits in your seat?
What happens if somebody sits in Steve's assigned seat?
The correct answer is 1/2.
The chase that the first person in line takes your seat is equal to the chance that he takes his own seat. If he takes his own seat initially then you have a 100% chance of sitting in your seat, if he takes your seat you have a 0 percent chance. Now after the first person has picked a seat, the second person will enter the plan and, if the first person has sat in his seat, he will pick randomly, and again, the chance that he picks your seat is equal to the chance he picks someone your seat. The motion will continue until someone sits in the first persons seat, at this point the remaining people standing in line which each be able to sit in their own seats. Well how does that probability look in equation form? (2/100) * 50% + (98/100) * ( (2/98) * 50% + (96/98) * ( (2/96) * (50%) +... (2/2) * (50%) ) ) This expansion reduces to 1/2.
An easy way to see this is trying the problem with a 3 or 4 person scenario (pretend its a car). Both scenarios have probabilities of 1/2. Did you answer this riddle correctly?
YES NO

Haunted Halloween House Riddle
To spice up your Halloween, you decide to enter a haunted house with your girlfriend. As you enter, an eerie silence embraces you and you can see nothing because its dark. You fumble your way and try your luck to find the switches, but it turns out to be a waste as there is no electricity connection to the house.
When you decide to turn back, the door closes on you and you are trapped in the house with your girlfriend who has now started panicking.
While you are trying to console her, an evil laughter takes you by surprise. Then, you see a faint figure who tells you that you have three doors in front of you and you must take one of them; it is the only way to free yourself. The figure describes that the first door opens up to a compact space filled with a swarm of deadly bees and you will be stung endlessly by them. The second door opens up to the electricity chairs. You both will be strapped to the chairs for five minutes and exposed to high voltage electricity. The third door opens up with a pit that has no bottom and you will keep falling endlessly into nothingness.
While this leaves you all panicked, which door will you choose if you have no other choice?

The cook says he put the money under a book on his desk to keep it safe. They check and it is no longer there. The maid says she moved it when she was cleaning to the inside of the book between page 1 and 2. They open the book and look between page number 1 and 2 but it isn't there. The mail guy says he saw it sticking out of the book and to keep it safe he moved it to between page number 2 and 3. Once they are done the culprit is promptly arrested.
