      +Mirage Uchiha -No-, it's: almost all numbers contain any one chosen digit. :P Intuitively obvious if one realizes that the longer the numbers are, the more digits they contain, and the more chance for a random huge number to contain your chosen digit.
      Bah, and yes, you're obviously right - when looked at it for more than five seconds I spent writing the comment - yes, almost all numbers contain any chosen number. Because infinity. :P

      @oranjizer 8 лет назад +24

      This doesnt make sense, i mean not what you said but what the video says.
      How can there be 3 in all the numbers based on the result being 1? If the result is 1 does it mean that the numbers which do not contain 3 is 0? Thats impossible because the sum of number which contain 3 and which do not contain 3 is supposed to be 1.

    • @TomaszWota
      @TomaszWota 8 лет назад +46

      LotusEater Not in all numbers - in almost all, as in - the larger the number, the higher the probability that it contains 3, and it tends to 1.
      And it's the reverse - probability of a number not containing 3 tends to 0 as the number grows.

    • @oranjizer
      @oranjizer 8 лет назад +1

      Tomasz Wota
      LOL how can the number not containing 3 tend to 0? there are always more numbers not containing 3 than there are numbers containing 3.
      Thats the whole point about the answer 1. That answer 1 is totally WRONG if the sum =1.

    • @capitaopacoca8454
      @capitaopacoca8454 2 года назад +7

      Now that you've rephrased it that way the whole thing is obvious. If you have a very large sequence of numbers (representing a big natural number), it would be quite surprising if there weren't a three there. As most natural numbers are really big ones, we can conclude the initial statement.

    • @debbiescott8520
      @debbiescott8520 2 года назад +1

      Except it doesn't, with the same logic the probability of any given number to NOT contain a 3 would be 1-(1/10)^n which tends towards 1 when n tends towards infinity. So with this logic, each number as a probability of 1 to contain AND to not contain a 3 when n goes towards infinity. But i think the whole point is the video was posted on the 1st of april.

    • @phiefer3
      @phiefer3 Год назад +4

      @@debbiescott8520 Actually your logic does not hold. The probability of a large number not containing a 3 would be (9/10)^n, as each digit has a 9/10 chance of not being a 3. What you found is the probability of a number not containing only 3s, which does tend towards 1.
      While the nature of the video may have been that it's a silly sort of thing to prove, the mathematics of the proof are accurate.

      Brown paper is so much better than a chalk board because you can save all your equations and then use it to wallpaper your bedroom. A chalk board just gets wiped off by some unknown entity like Mom or cleaning staff and then you have to do it all over again.

    I thought this sounded a bit ridiculous, but then I realised when you start getting into larger and larger numbers, each number has a lot of digits. When you start tallying up numbers with 100 digits, what's the chance there'll be _no_ 3's? Very low. So most numbers with, say, 100 digits, will contain at least one of each number between 0 and 9.

    • @StuartBradyAKAZub
      @StuartBradyAKAZub 9 лет назад

      Although of course, this can be generalised for other bases. :-)
      I guess you'd say: if b is our base (e.g. 10 for decimal, 16 for hexdecimal), then (b↑n - (b-1)↑n) ÷ (b↑n)) tends towards 1 no matter the value of b, so in hexadecimal, almost all numbers contain a 3 (albeit a different set of numbers to that in decimal), and almost all numbers contain any one of the hexadecimal digits.
      Cool fact, IMO: in binary (base 2), *all* positive integers contain a 1, not just *almost* all, although as you might guess, the number 0 does not contain a 1. However, almost all numbers contain a significant 0, just as in decimal.
      Also, the first significant figure of any non-zero integer in binary is always a 1, as there are no other options besides zero and leading zeroes are not significant figures. This is made use of in the storage of floating point (binary) numbers in computing, where the leading zero of any number is not stored, to save space for one extra significant figure (in the 'significand').
      BTW, a lot of interesting facts about numbers in decimal apply just as well in other bases (although sometimes for different sets of numbers), and it's amazing how different things can look through the eyes of a different base. The Hardy-Ramanujan number, 1729, doesn't look special in any way, unless you see it written in duodecimal or dozenal (base 12), under which it is written as 1001, at which point it becomes obvious that it's equal to 12 cubed plus one.
