Thank you for the confirmation.

thanks for ur help 

I have been asked to draw the winning numbers for the Rollin Christmas Lottery. I will be using random.org (The drawn numbers in order will be matched to usernames and prizes paid out).

Is this mean that everyone wear the same color? and because the king said "at least one of them was wearing the gold crown" then it means that everyone wear the gold crown.
Am I right?

I


Nah, I will figure you are cheating.
Better would be to Paint all the balls green or bury the red ones.

Answers to the second question.

1.
Incorrect.


2.
The first part is correct.
For if there have been just one gold crown and two silver ones, the one with the gold crown will immediate figure out that and would win it, but as it says in the question, it takes a very long time for the winner to get the answer, so the possibility is crossed out.

The second part is not correct because the king says the game will be fair to all three. If only the one who wears the silver can figure the color of the crown on his head, it would not be fair.


3.
No, because A could not immediately get the color of his crown. (explanation above)



4.
That is a pretty good solution lol.
But the emperor was wearing a huge crown made entirely of precious stones. Absolutely no gold used.



5.
No reflections lol. This is a logic kind of question, but anyway a good answer. Plus looking at reflections wouldn't tell the emperor who is wiser. May be both the crowns had the same weight, or was very small that it felt the same. The old men cannot compare since he cannot access the other.


6.
Incorrect, but You have got 2/3 of the explanation correct.

Winners of the first question paid.

Can I add my suggestion? if yest, I want to suggest to use the word "Mute" rather than "Ban" in the chat. Because it's obviously not a ban, it just a mute.

Thanks.
I'm sorry if my explanation is not that good

The answer is correct. (4 mBTC to Jeremycoin)

Original question:
You are a prisoner sentenced to death. The Emperor offers you a chance to live by playing a simple game. He gives you 50 black marbles, 50 white marbles and 2 empty bowls. He then says, "Divide these 100 marbles into these 2 bowls. You can divide them any way you like as long as you use all the marbles. Then I will blindfold you and mix the bowls around. You then can choose one bowl and remove ONE marble. If the marble is WHITE you will live, but if the marble is BLACK... you will die."

How do you divide the marbles up so that you have the greatest probability of choosing a WHITE marble?


Answer to my variant: (Best Explanation) (3 mBTC to fumblingperch)

Q. An emperor wants to find the cleverest of all men in his country to appoint him as his minister. There were three who made it to the last. The emperor places a crown on each of their heads, such that each man could see all of the other crowns, but none their own. Each crown was either gold or silver. The emperor gave his word to the wise men that at least one of them was wearing a gold crown; and that the contest would be fair to all three men. They were also not allowed to speak to each other. The emperor declared that whoever stood up and correctly announced the color of his own crown first would become his new minister. The men sat for a very long time before one stood up and correctly announced the answer. What did he say, and how did he figure it out?

hmm, i think i understand your idea ndnch... but i think there is a mistake in your question


The key words are

The emperor gave his word to the wise men that at least one of them was wearing a gold crown
and
and that the contest would be fair to all three men

the possible options, because it say it`ll be fair to all three men, so,
1. 2 guys using silver crown isnt fair, because the third man will know he`s using gold crown (unfair)
2. 1 guy using silver crown and 2 gold crown (possible)
3. 3 guys using gold crown - (possible)
4. 3 guys using silver - (impossible)

now we look at option 2 and 3... because other options not possible or unfair
if a guy see 2 gold crown, he can`t know if he`s using Gold(3) or Silver(2)

if a guy see 1 silver and 1 gold, he can know for sure that he`s using a gold crown (2), because option 1 and 4 not possible or unfair
so, the answer is he said is Gold Crown.

This is the only possible answer, the problem is.. you said it must be fair the all three guys

in option 2, the guys that can see 1 silver and 1 gold, can know the answer
so, two of the guys can answer it, but the third one (using silver crown, can`t never know)
so it`s only fair to 2 guys.
So... i think your question is wrong

My answer is> the question have a mistake, because the game was not fair to the 3 guys

A) if my life depended on this , i would cut the green and red balls in half and paste each half with the other half the other color. That way whichever ball is picked i would just flip the ball over to the color green not sure if that was prohibited .

B) the clever man who stood up would know what his crown was made of by looking at his reflection off the other men's crown. He also knew if his crown was gold or silver by determining if it felt heavy enough to be gold because gold is heavier than silver.

Q. You are to divide 9 balls - 4 green and 5 red into 2 boxes. You pick a box at random and a ball from it at random. If it is red, you DIEEEE!, if it is green (I will let) you live. How would you maximize your odds of living?

Let`s call the 2 boxes, boxA and boxB

the maximize odds for living is

boxA = 1 Green (100%)
BoxB = 3 Green and 5 Red (3/8)

as you have 50% to get boxA and 50% to get boxB, the odds to get a Green ball is:

(1 + 3/8)*1/2 = 11/16 = 68,75%

All other odds are lower because:

if you increase green balls in a boxA - it`ll continue at 100%, but will lower picking green ball at boxB odds
if you put only red balls in a boxA - your odd will be in max 50%
if you make a mist green and red - your odd will be in max 50% too (2green/1red and 2green/4red)

Finally I can figure it out
If I can put the ball by myself, I will put 5 red + 3 green in the first box and left the 1 green ball in the second box. So whenever I pick the box, I know that the box with just 1 ball on it is have the green ball.
And if I'm not allowed to put the ball by myself, I will just pick the box with less balls. Because the box with more balls is has to be the red ball in it

hmmm..and on the first question?..how should i maximize my odds of living...hmmmm...
simple...i'll use the balls and baskets as deadly weapons and try to kill you first....lol.. ;P

haha!.. not really sure how..but i'll find a way

the dude probably saw that the other two we're also wearing silver crowns...so he realized that all of them were probably wearing silver crowns..so he stood up and said: "Good game my emperor! GG...no one has the golden crown..only you, now can i be the minister?"



LOL...  

let's pretend that A is the wisest man .
because no one get picked so there won't be two of the golden crown
A think that there's only one guy wearing the golden crown , and that's himself because they are all wise man , and if they saw the golden crown more than one , they won't sat their for the long time to realize they're not the one got picked
They need to see both the silver crown to make sure that they are getting picked
So there's gonna be only one crown
A will stand up and said : i'm wearing the golden crown

Let me edit my own answer in a new post, as it doesn't add up
If someone would see two silver crowns, he would know he wears gold. This didn't happen, as they sat for a very long time, which means there are at least two golden crowns.
This means that one two persons see one silver and one gold crown, which means they still don't know a thing. That leaves the one person who sees gold only, he knows he is wearing silver. Hence he anounces: Iwear silver on my head and becomes minister.

He says the color of his crown.
How he figure it out? Simple, because of each man could see the others crown and there's just 3 of them with just 1 gold crown.
Which makes these possiblity :

• If he saw 2 silver crowns, then his crown is Gold
• If he saw 1 silver & 1 gold crown, then his crown is silver
