just because i don't like your signature, im gonna go ahead and just answer this one early.

An ump and a catcher

Correct sir.

PS. I have nothing against Parise. I've been a Devils fan for a long time, and I'm sick and tired of our franchise losing top class players for nothing (through UFA).

It's a long time since that we got some good assets in return instead of losing them for nothing.

Riddle # 2

There are three light switches in a three storey house marked A-B-C, two are up, one is down.

On the top floor there are three light bulbs in rooms 1-2-3.

Two are on, one is off.

You can only go upstairs once, to see what bulbs are on.

You have only one attempt at one switch (up or down) to figure out what switches control which light bulb(s).

Once you've switched a switch, you go back upstairs to figure out which switch controls which light bulb...

Turn one off and immediately go upstairs. Whichever switch is on obviously controls the light that is on. Then you feel the bulbs, whichever one still feels warm is the one you switched off.Correct sir.

I got one...

You are on a game show. There are three closed doors. Behind one of them is a car. You choose a door and then the host of the show opens one of the other doors, one they know doesn't have the car. He then gives you the option of switching doors. Why should you switch?

You switch because they

Riddle #3

A building in the desert. 300 miles from anywhere (in all directions)

This building is 50 feet high, 50 feet deep and 50 feet wide.

Inside the building is a metal beam 45 feet off the ground spanning wall to wall horizontally. ( five feet off the ceiling)

Hanging from the beam is a six feet piece of rope attached to it is a 36"x36"x36" box (inside is gold)

The box stands 36' off the ground.

There is only one door that is a standard 78"x30" to get inside the building (there are no windows)

The roof is as flat as the walls forming a prefect 50'x50' cube.

Outside is a flatbed 18 wheeler truck~there is nothing on the bed of the truck.

There are no ladders~only one man put the box where it is.

All that remains below the box on the ground is a pool of water about 2 inches deep.

How did one man get that box 36' above his head and tie it to the beam with no ladders and no help...

Reason for edit~~~bad math.

I don't think I understand your answer, or maybe I didn't explain the question well. First you pick a door that may or may not have the car. Then, whether you picked the right door or one of the wrong ones, the host opens one of the doors that does not have the car. So at this point you still might have chosen correctly the first time, either your door or the third door has the car. So why should you switch?Correct sir.

^{st}pick is right and a 66% chance one of the other 2 doors have the car. As they eliminate one door for you, there is a 66% chance the remaining door holds the car..

I'm going to guess it has something to do with filling the room with water so he could float on it until it was high enough for him to reach the beam. Not sure how the truck factors in or how he gets the water into the room though.Riddle #3

Nope, the odds that you pick the right door in the beginning are always 33%. It took me a while to understand this too. There are three possible outcomes:But that wouldnt matter because then the odds of your door having the car would increase

(1) You pick the right door in the beginning. You are then shown one of the wrong doors. If you switch you lose.

(2) You first choose wrong door A. You are then shown wrong door B. If you switch you get the car.

(3) You first choose wrong door B. You are then shown wrong door A. If you switch you get the car.

If you switch, there are two outcomes that result in you winning the car. The only way you lose if you switch is if you chose the correct door in the first place, but the chance of that happening is only 33%, so if you switch you have a 66% chance of winning.

I understand this but logically it still doesnt make sense, each door has 33% regardless of when it is opened to me...when they eliminate then it recalcs to 50-50

I corrected above to why i think it is still a 50-50

haha thats what Im saying! anyone have another riddle?i dont like the game show one. no matter what, those two remaining doors are going to have the same exact chance of having the car. the 3rd door's percentage should just be distributed equally to the two remaining doors

I am really curious to the answer for this. I find it interesting that they use 50'

**deep**. also the fact that its in the desert and there is a pool of water...

I became obsessed with this after watching the movie "21" it took me a while to understand it....

its called the monty hall problem : http://en.wikipedia....ty_Hall_problem

here is a simulator http://people.hofstr...ntyHallSim.html

i did 50 trials of each method.

when staying with my original door i had a success rate of 0.4 (20 out of 50)

when taking the switch i had a success rate of 0.68 (34 out of 50)

Bingo. The Wikipedia page does a good job explaining it.I became obsessed with this after watching the movie "21" it took me a while to understand it....

A simple way to demonstrate that a switching strategy really does win two out of three times on the average is to simulate the game with playing cards (Gardner 1959b; vos Savant 1996:8). Three cards from an ordinary deck are used to represent the three doors; one 'special' card such as the Ace of Spades should represent the door with the car, and ordinary cards, such as the two red twos, represent the goat doors.

The simulation, using the following procedure, can be repeated several times to simulate multiple rounds of the game. One card is dealt face-down at random to the 'player', to represent the door the player picks initially. Then, looking at the remaining two cards, at least one of which must be a red two, the 'host' discards a red two. If the card remaining in the host's hand is the Ace of Spades, this is recorded as a round where the player would have won by switching; if the host is holding a red two, the round is recorded as one where staying would have won.

This experiment is likely to approximate the probability of winning, and running the experiment over enough rounds should not only verify that the player does win by switching two times out of three, but show why.After one card has been dealt to the player, it is already determined whether switching will win the round for the player; and two times out of three the Ace of Spades is in the host's hand.

If this is not convincing, the simulation can be done with the entire deck, dealing one card to the player and keeping the other 51 (Gardner 1959b; Adams 1990).In this variant the Ace of Spades goes to the host 51 times out of 52, and stays with the host no matter how many non-Ace cards are discarded.

That switching has a probability of 2/3 of winning the car runs counter to many people's intuition. If there are two doors left, then why isn't each door 1/2? It may be easier to appreciate the solution by considering the same problem with 1,000,000 doors instead of just three (vos Savant 1990). In this case there are 999,999 doors with goats behind them and one door with a prize. The player picks a door. His initial probability of winning is 1 out of 1,000,000. The game host goes down the line of doors, opening each one to show 999,998 goats in total, skipping over only the player's door and one other door. The host then offers the player the chance to switch to the only other unopened door. On average, in 999,999 out of 1,000,000 times the other door will contain the prize, as 999,999 out of 1,000,000 times the player first picked a door with a goatâ€”the chance that the player's door is correct hasn't changed. A rational player should switch.

Intuitively speaking, the player should ask how likely is it, that given a million doors, he or she managed to pick the right one. It's as if Monty gives you the chance to keep your one door, or open all 999,999 of the other doors, of which he kindly opens 999,998 for you, leaving, deliberately, the one with the prize. Clearly, one would choose to open the other 999,999 doors rather than keep the one.

Alright here's my rethought answer...The 18 wheeler flat bed truck is VERY important...

The guy loads up the truck with enough blocks of ice that are small enough to fit through the door. He drives through the desert to the building at night during the winter so the ice doesn't melt (though I suppose this could depend on where the desert is located). He then stacks the blocks of ice on top of each other until he can climb them like a staircase to reach the beam and tie the box to it. As the temperature rises during the day, the ice melts leaving nothing inside except the box tied to the beam and the pool of water.
