What I don't get is how does that improve the chance of the prize being in that door if you switch? You said that if you switched doors, that your chance becomes 66.6%, but that doesn't make any sense because the host already said that one of the doors has nothing in it. Each door has 33.3% chance of having the prize when you eliminate one that means the chance switches from 33.3% to 50% not 66.6%, for you to have 66.6% you would need 3 choices, but since one door has been eliminated you only have 2 choices.

Here is a link explaining how you increase your odds. It took a visual for it to make sense to me.

Thanks I think I get it now. Since you only had 33.3% chance of getting the right door in the first place, and you learn that one of the doors is empty, then you know that it's better odds to switch.

actual answer logician B has a black and a white hat on and the hidden hats are a white hat and a black hat. Logician A and C both have 2 of the same color(either color works). Thats not enough for logician B to fighure out what hes wearing in the first round because he could have 2 of either color on himself. However, after the first round logician knows that he cant have 2 of either color hat on or one of the other logicians would have figured it out in the first round.

also the answer to number 2 is they will both be in chicago when they meet because they both left from detroit to go to chicago and the second one is going slower so the 2nd one wont catch the first one until it stops in chicago.

Suppose you live in a nation where families only want to have boys. Each couple in this country continues to have children until they finally give birth to a boy. If a couple has a girl, they have another child. If they have a boy, they stop having any more children. What then is the proportion of boys to girls in this fictional country?

1. Paul was walking in the middle of an empty road and saw a piece of gold and a piece of meat lying in the middle of the road. He took the meat and left the gold. Why?

2. There were two sexy ladies bathing nude in the river while a heterosexual man was walking by. Why did the man not look?

Also, it doesn't matter where they are going or how fast, when they "meet", they are in the same place, so they are the same distance from anywhere (New York, LA, etc...)
