@Gil-Gandel Yeah man, 100%. (Always were as far as I'm concerned.)

Yeah, there's got to be a better answer than "air" or "chaos" or "energy" for that one riddle.

Assoluto: I give you a question about free will in return that answers your question.

If someone prefers apple pie above any kind of cola, you know it, and you offer that person a choice between those two, does the person still have a free will or not? Or will that person only have a free will when he chooses cola?

If God is omnipotent and knows what we will do before he created us, how can we have free will?

God's word doesn't teach anywhere that anyone but Him has free will.

Here's an old one but goodie:

Times are hard in a small rural town--business is slowing and people are moving out. It so happens that there are two horse dealerships in town. Unfortunately, there's only enough people to support one of the dealerships. So the two owners meet and decide that one of them must leave town. Since neither of them want to leave they devise a competition to see who gets to stay. It is decided that they will race their horses across town. Now they don't want to damage their horses so they change the race rule so that whoever's horse crosses the finish post LAST wins the race and gets to stay in town. So the next day they set off. Both are ambling along taking rests and getting nowhere nearer to finishing. After a few hours, a wise old man tells them to dismount and gives them some advice, after which the two sprint back to the horses, get on and gallop towards the finish line. Assuming that the race rules were not changed - what advice did the old man give them ?

A man hijacks an aeroplane transporting both passengers(8 of them) and valuable cargo. After taking the cargo, the man demands nine parachutes, puts one of them on, and jumps, leaving the other eight behind. Why did he want eight?

Why did he want eight what? Other parachutes or passengers?

A man has two children. At least one of them is a boy. What are the chances that both of them are boys? (The answer is not 1/2.)

shoopi

At least one of the children is a boy, so that leaves three options:

a. The first is a boy and the second is a girl

b. The first is a girl and the second is a boy.

c. Both are boys.

Therefore the chance that both are boys is 1/3.

This is a good try, I was thinking something along these lines too at first, however, it is not the right answer.

Here's another riddle which is quite similar.

 

There's a hat with 3 cards in it. The first card has "X" marked on one side of it, and "O" marked on the other side. The second card has "X" marked on both sides, and the third has "O" marked on both sides.

You pick up a card, and look at one side of it. It has "X". What is the chance that it has "X" on the other side as well?

He told them to swap horses.

Shoopi: 1/2 that the other side has an x

2/3. You could be looking at the X of the card with XO on it, or either X of the card with XX. At least that's I'm assuming that's what it is. 1/2 is too easy.

This is right, and rest be assured it is mathematically correct.

Yes Smile How about this one? A new family with two children has just moved in next door. You look out your window and see the father playing with one of the children, who is a boy. What are the chances that both of the children are boys?

chasm1995

1/3 once again.

shoopi

This time it's 1/2.

Before it was given that at least one of the children is a boy.

Now it is given that one child is a boy and the second could be either.

See the difference?

chasm1995

Or, this just occurred:

seen: older boy has younger sister

seen: older boy has younger brother

seen: younger brother has older sister

seen; younger brother has older brother.

You see 1 boy, therefore there is a 1/3 chance that the other sibling is a boy.

A man was found dead in his apartment. He was sitting on a chair with his head lying on the desk infront of him. There was a gun in his right hand. There was also a tape recorder on the table. When the police entered the room and activated the tape recorder, they heard "I can't do this. I have no reason to live" and then a gun shot. How did the police immediately know that this is a murder case and not suicide?

.. but Why do we need to take into consideration the order of the children ? .. It's not mentioned that we need to ,I think.
