    A Paradox is an intersection of multiple factors where we assign a singular name. The singular tern creates mind farts when trying to understand an intersection

    In my opinion. A man should strive after God. Whether true or not believe in a higher power other than yourselves and your teachers in life. A pursuit to find God and then explore His understanding. Or just choose to spend hundereds of thousands of dollars at a college that is still learning extremely slowly itself, just to have a job or status. You will never see some of your work in this life come to fruition or an absolute answer for some of you.
    I am giving you a thought in your busy mind to pursue the Lord and His intelligent ways that baffle the wise of this chunk of dirt called Earth. It's called the Gospel 1st Corinthians 15 1-4.
    The Bible explained everything in this world in a time line so maybe if your truly honest in your study maybe you should give it a chance?
    Maybe that's all I need to say to get you curious or maybe the big bang theory is just a lie, told to get your trillion dollar debt as students to hold your future in slavery to the banking system.
    It's amazing how history explained the story of how we evolved into destroying ourselves though sin and suppression of the truth. The conclusion is not good before good gets here.
    I better go to bed before I start preaching and say something smart....

    Anthem is a good example of a paradox. It's a game that, if you play it, you get banned from it.

  • AdrianMaster

    I see Paradox as this for example:
    So you realise that in the future something bad is going to happen, so you do everything to avoid it and you succeeded, which, isn't possible?
    You knew the future was bad but the outcome was still different.
    I think a Paradox has something to do with Time and Space, Quantum Physics, Space Laws or just something that isn't Possible.

    I dont understand the monty hall problem if we know from when we enter the game show he going to remove a wrong option no matter if we choose the right or wrong door isnt that the same as having 2 options from the start. Since you have no way of knowing whether he picked a a door to remove randomly or if he picked a the other incorrect door.
    it was never a 1/3 chance to win because we know he had to remove a incorrect choice no matter what you picked. So at the start of the game when there was 3 doors it was still a 50/50 chance since we know an incorrect choice is getting removed.
    Edit: i know its statistically correct to improve your chances but that only applies because we initially think its a 1/3 chance when it never was

    • 『 』
      『 』 8 days ago

      +Klaus 74 did you not read my previous comment u explicitly stated that switching gives BETTER odds the whole point im trying to make is that safe bet is not always the correct bet when dealing with gambles in where if 1 is choice right the other is wrong

    • Klaus 74
      Klaus 74 8 days ago

      First, it can't be 50/50 because it's impossible for the host to have a 1/2 chance of leaving a goat to switch with. And secondly, since this is a conditional probability problem the new information is that he WILL open a non-prize door, so before the reveal we know the probabilities of all three doors and where one of them is.

    • 『 』
      『 』 8 days ago

      +Klaus 74 it seems i didnt explain properly i know statistically switching gives you better odds but only because we initially a 1/3 in chance by temoving a wrong choice we now have a 66% chance if we since we are picking 2 doors 1 that he revealed and 1 that we dont know. What im trying to point out is that its all because we believe that the higher chance outcome is gonna be the outcome that comes true which is not the case.
      Edit: probabilty gets more accurate when tested multiple times if only tested once as an individual your probably going to only enter that gameshow once in your lifetime if we are talking about contestants winning then yes switching is best for the contestant but not the individial

    • Klaus 74
      Klaus 74 8 days ago

      So if you started with 2 doors and you know the host will add one with a goat after your guess, would you have a 1/3 chance of having picked the correct door? Not a chance.

      It has a million answers but let's concentrate on two given aspects of information, daughter and mother. So boils down to 2 answers. Neglecting the condition of "she" is someone else than both, mother and daughter. Depending upon the condition who you are and who you consider "she" is,
      3. Unimaginable amount of individualistic person's.
      4. Infinity people added up to one.
      5. A limit of person who is underdeveloped, to be considered reaching full.
      6. ....
      I can go on about these answers for infinity.

    How is example 3 not a 50/50 chance? From the vantage point of one scenario, that being only two remaining envelopes, it is a 50/50 chance. When there are 3 envelopes it is a different scenario. The whole switch aspect is an illusion if you only consider the odds based on the original 3 envelop scenario.

    • Klaus 74
      Klaus 74 18 days ago

      That's right. A 2/3 chance the host has a right/wrong set of envelopes because there's a 2/3 chance the contestant picked a losing one. The host is forced to reveal the other losing one so he still has the prize 2/3 of the time.

    • Shawn Briggs
      Shawn Briggs 18 days ago

      +Klaus 74 So we are considering the odds that the host has of having the correct envelope? If that is the case, I think you helped make it click. Thanks!

    • Klaus 74
      Klaus 74 18 days ago

      If you have a 1/3 chance of picking the right envelope then there's a 1/3 chance that the host has two wrong envelopes. Do you think there is a 1/2 chance he can leave one of them to switch with?

    Guys the achilles and tortoise paradox is incorrect. He said that for every 100 meters achilles runs, the tortoise walks 1 meter. Then, right after, he said achilles ran another 1 meter to get to 101 meter, but the tortoise moved another meter. The tortoise should not have moved one meter when he ran 100 meters and also move one meter if he only ran one meter himself. So actually he would catch up to the tortoise easily.

      Don't be silly. Take three pieces of paper, two marked 'lose', one marked 'win'. Place them randomly face down and move one to the side. That is your first guess. Turn all of them over. If the 'win' is among the two you didn't pick that's a win by switching because the host has to leave it for you after revealing the other one.

    • Klaus 74
      Klaus 74 19 days ago

      Lol....so if we both pick the same envelope and agree upon staying with it, I would have a 1/3 chance of having the right one if it was opened immediately and you would have a 1/2 chance if you waited for the reveal first. Hilarious!!!!

    • Hotwheels Racing -Bill Gould
      Hotwheels Racing -Bill Gould 19 days ago

      +Klaus 74 SMH....OMG you need to use your listening and reasoning skills bc you obviously have none. After it was revealed he/she was able to repick..the key word is repick. It now erases the 1st rd of picking when there were 3 choices. Now 1 was eliminated. Thus leaving only 2 Choices..you can never have a 1/3 chance with only 2 Choices. Ever! its 1st grade math.

  • Retar Joe
    Retar Joe 19 days ago

    So in the Monty Hall paradox, it is only correct to switch, if YOU know, that the HOST knows where the prize is.
    If the host didn't know where the prize was, and you know he didn't know, and opened a door at random to reveal a dud, there would be a 50% chance at winning regardless if you switched or not.
    If the host did know where the prize was, and you didn't know he knew, it would be the same as the host not knowing (from your perspective), and there would be a 50% chance at winning regardless if you switched or not.
    If the host did know where the prize was, and you know he knows, there would be a 66.6% chance at winning by switching.

    Certain conditions is required for the Monty Hall paradox to take effect.

      ​+Klaus 74 You are absolutely right, I completely misunderstood your statement. I was trying to argue something else besides your point.

    • Klaus 74
      Klaus 74 19 days ago

      I understand exactly what you are saying. You are the one that keeps bringing up the variants and I'm correcting them as we go along. Again, the probability is determined by the knowledge of the host, and not by the lack of knowledge by the contestant. There is NOT a 1/2 chance of winning by staying if we don't know whether or not the host deliberately or randomly reveals a non-prize, it is EITHER 1/3 or 1/2. That is why we should always switch if we don't know because those chances are either 1/2 or 2/3.

    • Retar Joe
      Retar Joe 19 days ago

      +Klaus 74 No, it is not. I would explain it to you again, but I already did in my previous comments.
      I can simplify it to you - your math is correct, granted that we act within the rules of the Monty Hall Paradox, rules here is that we know that the host will reveal a dud and give us the chance to switch.
      If we don't know that the host knows, we are not acting within the rules of the Monty Hall Paradox, and the whole system changes.
      I strongly suggest you look up the paradox as well as the possible host behaviors in unspecified problems, as there is a difference - and I don't think you understand the point I'm trying to make.

    • Klaus 74
      Klaus 74 19 days ago

      You said in your first comment that there must be a 50/50 chance of winning by staying if we don't know about the host's knowledge. That is simply not true. The chances are either 1/3 or 1/2, and the switching chances are either 1/2 or 2/3. The probability is determined by the knowledge of the host and not by the lack of knowledge by the contestant.

    The classic paradox of
    "Can an almighty being make something to heavy for even it to lift"
    Is based on a definition having two contradictory premises
    1. An almighty being can make anything including an object that takes away it's power. If not then it's not ALL powerful
    2. If an object exists which can take away it's power then it never was ALmighty. Just "really"mighty.
    Thus if 1 not 2 if 2 then not 1. And of course if something isn't both its not Almighty. The idea defeats itself.
    The world can have either immovable objects or irresistible forces not both. (Which one it has i do not know)
