What toilet? I said that he had nothing except the clothes on his back. That means theres no toilet xD.

Poor man.. alone, no toilet, no food, no water.. must hurt.

And regarding the car behind the door riddle: whichever you want; the odds are 50%/50%.

He can't see anything outside his cell, how does he know where the keys are? and also if he can't see anything, and there is nobody to contact, how does he know there is a reliable source of food and water?

Has nothing to do with anything I'm sure, but im curious

I should, if i choose door A i got 2:3 chance to win. but if i had stayed with door B, it would be only 1:3 chance to win.

I never actually said that the man knew where the keys were, I'm just saying that for the readers benefit.

About the relaible source of food and water, I suppose it's an eating area or something... Maybe theres a well there...

Want to share your reasoning behind this? If the host (Monty something) reveals that door C is empty, then there are only 2 possible options to where the car is. Because the car has an equal chance of being behind each door, the chance is the same for each door, i.e 50%. If you really want me to, I'll draw you a tree diagram to prove my point.

Btw, the 50% chance was why I said I did not know the answer in my previous post. Usually riddles require a definite answer (in this case, switch or don't switch), or have a 'trick' answer.

It's the old Monty-Hall puzzle (Let's Make a Deal). There are three possible scenarios, each with equal probability (1/3):

#1 You pick gate number 1. The game host picks the other gate. Switching will win the prize.

#2 You pick gate number 2. The game host picks the other gate. Switching will win the prize.

#3 You pick the gate with the prize. The game host picks either of the two other gates. Switching will lose.

Therefore, switching doubles your chances of winning.

He opens the door, it wasn't locked.

Lol finally someone gets it. I've heard lots of crazy responses but it's not really that hard.

Actually, switching only doubles your chances of winning if you would have picked the gate with the prize. If the prize is behind gate B, and you pick C, then switch, you win. If the prize is behind B and you pick B then switch, you lose.

At noon and midnight the hour and minute hands are exactly coincident with each other. How many other times between noon and midnight do the hour and minute hands cross?
not hard at all if you think

Until I am measured, I am not known. Yet how you miss me, When I have flown.

too easy.. the answer is time..

lets try something a little harder:

What is the missing symbol (?) in this sequence
A A A A ? A A A A A A

Here, lemme try to explain it.

Situation: The car is in Door B. Here's what you can do:

You pick Door A, and the host opens Door C to show that nothing is in it. You switch, you win.

You pick Door B, and the host opens Door A or C, doesn't matter which. You switch, you lose.

You pick Door C, and the host opens Door A to show that nothing is in it. You switch, you win.

The same thing for when the car is behind Door A and Door C. You originally have a 67% of the car being behind one of the doors you didn't pick. So when the host opens the other door, there is a 67% chance that the prize is in the door that you could switch to.

And whoever said the name of the show might affect the riddle, it doesn't. It's just a situation to set up the riddle.

Etrik · Dec 10, 2006, 01:38 AM // 01:38

First example. If you pick A and it's not behind C, there's a 50/50 chance it's behind either A or B. So I don't see how switching makes you win, since it has a 50% chance it's behind A, the one you initially picked.

Second example. You pick B. He opens C, it's not there. 50/50 to be behind B or A. He opens A, it's not there. 50/50 for it to be behind door B or C.

Third example. You pick C. He opens A, it's not there. 50/50 for it to be behind B or C. Same thing, really.

Relam, the 67% chance argument is flawed. Originally, there's a 33.(3)% chance it's behind either door. Once he opens one and shows it's not behind that one there is a 50% chance it's behind either of the doors.

Relambrien · Dec 10, 2006, 01:53 AM // 01:53

Alright, think of it this way:

You pick Door A.

If the car is behind Door A, you switch, you lose.
If the car is behind Door B, the host HAS to open C, you switch to B, you win.
If the car is behind Door C, the host HAS to open B, you switch to C, you win.

2/3 (~67%) chance of getting it if you switch.

You pick Door B:

If the car is behind Door A, the host HAS to open C, you switch to A, you win.
If the car is behind Door B, you switch, you lose.
If the car is behind Door C, the host HAS to open A, you switch to C, you win.

2/3 (~67%) chance of getting it if you switch.

You pick Door C:

If the car is behind Door A, the host HAS to open B, you switch to A, you win.
If the car is behind Door B, the host HAS to open A, you switch to B, you win.
If the car is behind Door C, you switch, you lose.

2/3 (~67%) chance of getting it if you switch.

Clearer now? There's no other way I can explain it, oh wait, yes there is. Time to use 100 Doors (thanks to Team-iQ for the explanation idea).

Since it doesn't matter which door you pick, let's say you pick Door 1. The host opens 98 other doors showing that there is nothing behind them. The one door remaining then has a 99% chance of having the car. Here's some examples to show what I mean.

You pick Door 1:

If the car is behind Door 37, the host opens all but 1 and 37, you switch, you win.
If the car is behind Door 78, the host opens all but 1 and 78, you switch, you win.
If the car is behind Door 43, the host opens all but 1 and 43, you switch, you win.
If the car is behind Door 16, the host opens all but 1 and 16, you switch, you win.
If the car is behind Door 84, the host opens all but 1 and 84, you switch, you win.
Etc. Ninety-nine times out of 100, you switch, you win.

The person who posted the riddle (you?) didn't mention he always opens a door that doesn't contain it.

And both arguments win. It's all about perspective, imho.

Well, if he opened the door that did contain it, then there's 0% chance of winning, so I figured it was obvious he never opened the door with the car.

But I'm glad you understand the logic behind it :P

Three gods A, B, and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for “yes” and “no” are “da” and “ja” in some order. You do not know which word means which.

Etrik · Dec 11, 2006, 06:00 AM // 06:00

I don't know. Spill the beans, way too much thinking involved.
