That’s not how that works.
Doesn’t it depends on whether we are talking about real or integer numbers?
EDIT: I think it also works with p-adic numbers.
No. In the set of real numbers it is still very possible to randomly select a number that can be written with finite digits.
No it wouldn’t. You don’t understand how random works
No, if truly random it could be any number from 0 to infinity. The randomization doesn’t impart any qualities to the selected number.
If you randomly selected numbers from the infinite range of numbers for an infinite number of time, you would get a result of “7” just as often as getting “3.456e11”.
The probability of getting a finite number is pretty much zero.
For any range [0; n], where n is finite, there are always infinitely many numbers larger than n, so the probability of getting a number in said range is n/(n+infinity). I feel very confident in saying that something with that probability will never happen.
I see what you’re saying (assuming you mean a random integer from 0 to infinity), but it couldn’t really, since there’s no such thing as an integer with infinite digits - any random integer will have finite number of digits.
The real problem is there’s no way to choose a random number from 0 to infinity. Every finite number has a probability of 0, and in fact, for any number you choose, there is 0 probability that it will be less than that number. Note that 0 probability is different from “impossible” - see https://en.wikipedia.org/wiki/Almost_surely
I think it’s right
Edit:
TIL: when saying random numbers, some people think to integers, others to real numbers.
I also think that’s correct… if we are talking about real numbers.
People are probably thinking about integers. I’m not sure about OP.
EDIT: I think it also works with p-adic numbers.
Yes real numbers, but as far as I’m aware it’ll happen for integers too almost surely
I think you’re confusing “arbitrarily large” with “infinitely large”. See Wikipedia Arbitrarily large vs. (…) infinitely large
Furthermore, “arbitrarily large” also does not mean “infinitely large”. For example, although prime numbers can be arbitrarily large, an infinitely large prime number does not exist—since all prime numbers (as well as all other integers) are finite.
