Mathematical Logic [part 2]

The first time I started a thread like this was maybe about a year ago and it turned into a mathematical theory thread which was still pretty cool.

So here's a riddle my math teacher gave me yesterday, I didn't get the answer but hopefully, it won't trick all of you. PM me your answers. Two guesses per person. I'll post the answer and who got it right tomorrow. Winner starts a new riddle.


A man is going home. He sees a man with a mask on, turns around, and walks the other way. What is the story behind the first man's strange actions? Who is the man with the mask?

Have fun!

This is an unsolvable "riddle" - there are more than one "correct" answers.

Umm, neither of you are correct. Try to stick to question I can answer yes, no, or irrelevant to.

So far, two people have gotten it correct.

Fine. Do you realize that this "riddle" cannot be solved, as the solution requires a specific school of thought, not logic in general?

Freedom of speech is the basic freedom of humanity. When you've lost that, you've lost everything.

Alright then, BMWboy, d0rk, J.Burnaway, and Gonzotek had the correct answer. Its coming out messy, so from now on just post the answers here. First person to get them correct posts a new one. Here's the next logic problem.


Imagine that you have three boxes, one containing two black balls, one containing two white balls, and the third containing one black ball and one white ball.
The boxes were originally labelled for their contents (BB - WW - BW) but someone has inadvertently switched the labels so that now every box is incorrectly labelled.

Without looking inside, you are allowed to take one ball at a time out of any box that you wish, and by this process of sampling, you are to determine the contents of all three boxes.

What is the smallest number of drawings needed to do this?

2 in the best case - I can explain it if you want me to. But first tell me if I'm right please!

Mia

And could you please post the answer to the last one?

Mia, I will post the answer once someone guesses correctly. But remember, an explanation is needed in any case. Otherwise, there is no logic involved.

The answer to the last one was: The man walking home was a runner at third base. The man in the mask was the catcher at home plate with the ball. The first man turned around and returned to third base.

The question isn't for the "best case". You have to say how many it will take no matter what the situation is.

I think it is just one no matter what case it is, it just depends on what box you take the balls out first, (or matybe I'm completey wrong and GoldenSphynx is laughing at me)

Well I think I'll just go ahead and explain my answer although it doesn't seem to be right:
You take one ball out of the "BW" box, let's say it's black (it works the other way jsut the same) so you know that there must be the two black balls for every box is incorrectly labelled (there can't be the BW option because it would be correctly labeled and the statement form the question wouldn't be true).

So then you know the in the "BW" bow are two black balls, then you know that in the "BB" box can't be the white and the black ball because then they would just be switched and the "WW" box would be correctly labeled.

So the "BB" box must contain the two while balls and the "WW" box must contain the white and the black ball.

In case you drew a white ball at the very beginning, the content of hte "BB" and the "WW" box would be switched.

What's wrong with that answer ????

Mia

Thank you!

I hope nobody knows this already...

A man goes to an old temple with 3 speaking statues. He was been told that there's
  • one statue of truth (it always tells the truth no matter what your'e asking),
  • one statue of the Lie (it always lies to you no matter what you ask it) and
  • one Diplomatic statue (It sometimes tells the truth and sometimes lies, you never know)
BUT nobody ever knew which statue was which. (They're all stnding in a row)
  • That man went to the statue on the left and asked: "Who is standing next to you? (=in the middle)"
    Left Stature: "The statue of truth"
  • He asked the one in the middle: "Who are you?"
    Answer from the middle one: "The diplomatic statue"
  • He asked hte one on the right: "Who's standing next to you?(=in the middle)"
    The statue on the right answered: "The statue of the lie"
So which statue is which?


Please post in te order left - middle - right and I'll post if your'e right and you can give the explanation!
Have fun!

Mia

Let D = Diplomatic Statue
Let L = Lie Statue
Let T = Truth Statue

The order from left to right is D L T

Start from the right:
He asked the one on the right: "Who's standing next to you?(in the middle)"
The statue on the right answered: "The statue of the lie"

The T statue told the truth, the L statue is in the middle.

---

He asked the one in the middle: "Who are you?"
Answer from the middle one: "The diplomatic statue"

The L statue lied. It is not the D statue.

---

That man went to the statue on the left and asked: "Who is standing next to you? (in the middle)"
Left Stature: "The statue of truth"

Doesn't matter since it could be true or false since it's the D statue.

Any of the statues could be the diplomatic statue. The left one could also be the lying statue, but could not be the truth one. The middle one can also be the lying statue, but can not be the truth one. The right one cannot be the lying statue because then the others wouldn't be following their rules. So the right one is the only one that can be the truth statue, which means the middle one is the lying statue, so the left one is the diplomatic.

Here's my riddle. Will post when someone gets it right.

Think of words ending in -GRY. Angry and hungry are two of them. There are only three words in the English language. What is the third word? The word is something that everyone uses every day. If you have listened carefully, I have already told you what it is.

Seems a little disjoint here.

Third word of what?

Third word that ends in -gry?
Third word of the three word English language?

What is the largest number you can write using only 2 digits? Just 2 digits, and nothing else.

Using hex, FF is 255, or if you only want to use numbers 99 is 153.

The -gry stuff is just misdirection. "language" is the third word in the phrase, "the english language".

I'll rephrase the riddle in a way that draws attention to what it's really asking:

Quote:

get it now?

and infinity squared is the largest number you can represent with two digits...draw two eights one on top of the other, then turn the paper sideways.

You're wrong. If you draw two 8's correctly, you can get infinity to the power of infinity.
