LATERAL PUZZLES AND RIDDLES

The light from the sun let him see it? :s

I suppose thats correct. The answer is that it was daytime.

Even in direct sunlight you wouldn't be able to see something black against something black, surely?

Even the dog being a potato would make more sense.

Idon't know. Different shades of blackI guess. I just found it on a riddle website.

A man lives on the twelfth floor of an apartment building. Every morning he takes the elevator down to the lobby and leaves the building. In the evening, he gets into the elevator, and, if there is someone else in the elevator -- or if it was raining that day -- he goes back to his floor directly. Otherwise, he goes to the tenth floor and walks up two flights of stairs to his apartment.

Why?

[Constantinople]

The elevator has room for one only and is not waterproof. The elevator is also under maitenence on the 11th floor, thus it being only able to reach floor 10.

THE MAN'S A MIDGET

[killa]

The man is a midget. He can't reach the upper elevator buttons, but he can ask people to push them for him. He can also push them with his umbrella. I've usually heard this stated with more details: "Every morning he wakes up, gets dressed, eats, goes to the elevator..." In the other direction, for a shorter problem statement, leave out the "someone else in the elevator" and "if it was raining" parts, and just say on his return to the building he always goes to the tenth floor. Ron Carter suggests a nice red herring: the man lives on the 13th floor of the building.

Monty hall problem

After winning a gameshow you re given the choice of three doors. Behind one is a brand new car, behind the other two are goats. Lets assume you dont want the goats.

You pick a door, after you make your choice the host (who knows what is behind each door) opens one of the doors you didnt choose, to reveal a goat. He then asks you if you wish to change your choice from the door you picked initialy to the remaining door. Should you change and why?

A blue house is made of blue bricks. A yellow house is made of yellow bricks. A red house is made of red bricks. An orange house is made of orange bricks. What would a green house be made of?

Yes

the car can be in door 1, 2 or 3 so the possible arrangements would be:
car, goat, goat
goat, car, goat
goat, goat, car

Assume you pick the same door each time (the 1st one) so in the first scenario, changing would give you a GOAT.
In the second scenario, changing would give you a CAR.
In the third scenario, changing would give you a CAR.

So 2 out of 3 times you get a car if you change.

[CircleBoy]

You're right, though yourt wording/logic is a bit off

http://en.wikipedia.org/wiki/Monty_Hall_problem for proofs and stuff

Best way ro phraze it is you either picked, with your first choice, a car, goat one, or goat two

if you picked the car then swithcing nets you a goat
if you picked either goat switching gets you a car

Switching is to your advantage 2/3 times.

[CircleBoy]

Ok, let me try and explain this as simply as possible

We're going to go through a game making ALL POSSIBLE CHOICES.

In this particular game door one is the car and doors two and three are the goats.

Player that switches- If this player picks door 1 then door 2 or 3 is revealed to have a goat behind it, when they switch they just switch to the other goat door and loose

If this player picks door 2 then door 3 is revealed to have a goat behind it, when they switch they will switch to door 1, and win

If this player picks door 3 then door 2 is revealed to have a goat behind it, when they switch they will switch to door 1 and win.

The switching player wins two out of the three possible games.

Player that doesn't switch- If they pick door 1, they get the car, stick with it and win
If they pick door 2, they get a goat
If they pick door 3, they get a goat

The non switching player only wins 1/3 times

Considering that one was difficult for some to understand, here's a similar but more simple one.


You have just died and you are in a room, there are two doors in the room. One of the doors leads to heaven, one of the doors leads to hell. There is one person guarding each door, one of the people will always tell a lie, and one of the people will always tell the truth, but you do not know which one is going to tell the truth. You can only ask ONE question, what do you ask and to whom do you ask it?

"Does this door lead to heaven?" to the man guarding the heaven door. God would not hire a guard that lies as lying is a sin.
