    The video does a good job of explaining the answer of this specific scenario. It would have been even better to generalize the solution for those not familiar with formal logic. Not just for cycles and licenses, but *every one-way condition* A -> B has a companion condition NOT B -> NOT A. That would elevate the video by adding some take-away knowledge to the fun.

      Thanks for your suggestion! That’s a great point about generalizing the solution for quick understanding. I must share your point in any of the upcoming videos.

    You got me in this one, I underestimated the problem and thought only A should be flipped, next time i will be more cautious. Great explanation btw!

    There’s a part of me that thinks if we can’t trust “the rule” we probably shouldn’t trust “the given” either, in which case we must also check the D for the presence of a vowel on the other side as a rule violation.

    • @LOGICALLYYOURS
      @LOGICALLYYOURS  5 วันที่ผ่านมา +3

      I certainly understand your point. The given data can always be trusted. It’s only the “Rule” that needs to be verified…. At least in theory

      This is the issue I had with this puzzle as I've seen it or a small variation before. I get the intended solution, but practically if your factory can misprint even/odd numbers, it can misprint letter/number and end up with two letters, two numbers, maybe blank faces (out of ink), upside down or inverted images, etc... the separation of "given" and "rule" is kind of arbitrary and is not how QC is done in practice.

    • @noodle_fc
      @noodle_fc 5 วันที่ผ่านมา +3

      ​@@Gideon_Judges6 But this isn't a video about how QC is done in practice. It's a logic puzzle. Logic puzzles contain arbitrary givens and rules. It delivered exactly what it promised but you're unhappy that it wasn't something else? If we're doing hypotheticals, just pretend there are people ahead of you on the QC pipeline who have already checked those other conditions. But really the best thing would be to take the puzzle as written because you're doing yourself no favors going to an Italian restaurant asking for Chinese food.

    This is if A implies B is equivalent to ~B implies ~A . A card has to turn to see other side is even .and 7 has to turn to see it's not vowel. Listen to you after so many days

      Google, what happened in AD 47?
      Google: In AD 47, the Romans established a settlement on the River Thames, a settlement that would become the city of Londinium. The settlement was situated at a bridgehead on the north bank of the river at a ford, where a major road nexus would converge at a bridge crossing

    Noooo, was waiting for the answer to the archery puzzle from last video 🥲.
    That said I grossly misunderstood the question. I thought the relationship was enforced both ways, i.e. if a card is vowel number is even, if number is even must he vowel and shouted "ah this puzzle is a trick! You need to flip all of them!"
