    Damn, scanning the QR at the beginning of the video takes you to: ua-cam.com/video/dQw4w9WgXcQ/v-deo.html
    Which is a really cute puppy video, loved it

      Cute puppy video gave me flashbacks
      UA-cam was Rick rolled and my theory states that UA-cam was so mad that they removed the dislike count

    just think about this: each human alive could create quadrillions of codes per second, all at once, and it would still last megazillions of years before we ran out of codes

    What is the probability that two code qr are identical?

    • @H3Vtux
      @H3Vtux  2 роки тому +4

      1/whichever number I showed being the amount of combinations. So for a 21X21 it's 1/the number at 1:05
      though methods are taken to prevent them from being the same, so in reality the probability is even lower, down to essentially 0.

    Please explain why your using 2 as a base to calculate the total number of possible combinations at 00:57 of your video...didn't get that.!!

    • @H3Vtux
      @H3Vtux  2 роки тому +1

      Because anything with two values is base 2, and in this case either square can be black, or white. If each square could be black/white/red/green/yellow/orange/brown/grey/blue/purple then base ten would be the correct choice because there are ten "states" that each square can be in. For this each square only has two states, so it's essentially a really long base 2 number.

    • @karanrajak_19
      @karanrajak_19 Рік тому

      Because there is only two characters 1 or 0
      Black = 1
      White = 0
