Re: A math Problemhackenslash wrote:leroy wrote:I could have not typed a number with trillions of digits because long before that I would have died yes it is relevant because your whole argument is based on the assumption that it is possible to type (or think about) any real number. ................there are numbers that are impossible to think about or type because they have so many digits. ok if you use exponentials you can write a number with trillions of digits, but even with exponentials you will get to a point when a number is so large that it would be impossible to type it (given my limited time, limited computer memory, etc.) hackenslash give up, selecting a random number is not an event with 1/ infinite possibilities there is always a limited amount of numbers to choose from, "events with a zero probability happen all the time"

Re: A math ProblemGrumpy Santa wrote: No that is exactly that part that I don't grant 4287 belongs to the set of real numbers that can be typed in a computer ................which is a finite set for example assuming that I will only live 100 years from now, assuming that theie is the only barrier that limits my options, the set will only include numbers that are possible to write in 100 years, even with exponentials, the set would still be finite. I would also say that 4287 or any other small number with few digits is more likely to be typed than a number with millions of digits .............not all the numbers have the same probability of being typed. I am presumible more likely to waste a few seconds writing a random number than wasting 50 years So in short, the set of real numbers is infinite, but the set of numbers that are possible to type in a computer is finite.......agree?

Re: A math Problemleroy wrote:Grumpy Santa wrote: He's right though if you're talking about a pure random sampling from that infinite set. You're talking about two different sets of numbers here, an infinite one and a very big yet finite one that you seem to be describing. Do you acknowledge that you're not talking about the same set of numbers that he is? Do you understand that infinity is not a number, but instead is a concept? Do you understand that any number divided by infinity is, by definition, zero? By the way, you example, where you're going out to trillions of numbers, is actually going harm. You need to look up the concept of "effectively negligible". Things with fantastically small but positive probabilities are said to be effectively negligible, or effectively zero. Scientists don't believe. They conclude based on evidence.

Re: A math Problem
Greetings,
The chance of you picking a number is 1 in infinity. This is simply a fact. Noone knows whether you're going to limit yourself to a certain number of digits or not when you choose to type a number. You could have written 4287^7824  which is a real number capable of being typed into your computer.

Re: A math Problemleroy wrote:Grumpy Santa wrote: Well, since you're being completely dishonest and cutting out the part where I was saying you were right I'm not going to give you this one. It is a fact that 4287 is indeed a part of an infinite set and under that understanding he's correct. This is a fact, Leroy. Quit jerking around this. I also acknowledged that you're using it as a part of a finite set, and that changes things. However depending on the size of your finite set as a whole you could still be dealing with what's known as an effectively negligible probability, or a zero probability. So, if you're going to at least simulate being completely honest, state the size of the set you're using with regards to coming up with a random number. Look, I and everyone else here understands where you've shifted your argument... a person is most likely to pick a random number from within a very narrow range. But you're using that to talk past the argument while ignoring simple facts. Scientists don't believe. They conclude based on evidence.

You ignored these: Do you understand that infinity is not a number, but instead is a concept? Do you understand that any number divided by infinity is, by definition, zero? Shameful. Acknowledging these doesn't harm your argument, it just helps show where you're talking past each other, that's all. If you look at Dragon's last reply it's clear that many are talking about an infinite set of numbers, be honest and admit that. I understand that you're talking about a finite set. C'mon man. Scientists don't believe. They conclude based on evidence.

Re: A math Problemleroy wrote:Grumpy Santa wrote:You're being aggravatingly dishonest Leroy. You ignored these: My apologies, but with the use of exponents and other algorithms to represent numbers that's actually no. I know, that's picking nits, and you're actually approaching this wrong. Forget about the capabilities of the computer, it's irrelevant. For what you're trying to explain you need to consider the capabilities of the average human mind and the likeliness that the average person won't come up with Avagadro's number to the square of Pi at random but more likely a positive integer less than 10,000. There will be exceptions of course. So, it's true that if a number were selected at random (just purely random, not by a person) then that number would be selected from an infinite set and would, by definition, have had a zero probability of being selected. This is simply a fact, please admit it. You're saying, however, that a random number chosen by a human mind as a processor will come from a finite set which is bound by the imagination and processing of that individual mind, which will vary. That's my understanding of your argument, and if so, it's correct. There's a limit to what the human mind can simply comprehend. We evolved with the capacity to quickly and easily grasp concepts and quantities that helped with our survival, and those numbers are much closer to zero than not. So two things are effectively demonstrated here... yes, zero probability events can indeed happen (and do all the time), and the human mind is unable to comprehend infinity and incorporate that concept in the random choosing of numbers. Scientists don't believe. They conclude based on evidence.

If you're simply claiming that you didn't think of using exponents when you typed a number, that doesn't change the fact that the chance of you typing a number is 1 in infinity. If you're excluding the use of exponents, then that's a limit you're placing on yourself  it's not an absolute limit. You could even have typed 4287^infinity or infinity^4287  which is larger? There are no limits to the numbers that you  or anyone  can type into a computer. leroy wrote:o wait I forgot, you aee an atheist and therefore you are not suppose to prove anything, Being sarcastic is not going to help you win this argument, leroy.

Re: A math ProblemGrumpy Santa wrote:My apologies, but with the use of exponents and other algorithms to represent numbers that's actually no. nope, even with algorithms, exponentials, decimals etc. the options are still finte ..........and I can prove it if you ask me to. .

There will be exceptions of course. yes and you ll be surprised to see that most people in this forum would disagree with this statement, thy would argue that Avagadro's number to the square of Pi has the same probability of being selected than a positive integer less than 10,000, So, it's true that if a number were selected at random (just purely random, not by a person) then that number would be selected from an infinite set and would, by definition, have had a zero probability of being selected. This is simply a fact, please admit it. NO, that is my main point of disagreement, humans computers robots and calculators would also be selecting from a finite set, for example my hand calculator can only select numbers with 12 digits or less.
and the same is true for calculators robots, computers etc. they also have limits "events with a zero probability happen all the time"

And who is making the random selection? a computer? a robot? a human? lets see if we can agree with this statement If one select a random number from the set of real numbers, the probabilities of selecting a particular number would be 1 / Infinity (or Zero) but there is not an existing mechanism (computer, human, robot etc.) that can do such selection, any known mechanism would select from a finite set of numbers. (for example my hand calculator could only select from numbers that have 13 or less digits which is a finite set. ) hopefully you agree and we can close this conversation, if you disagree well I would not have anything else to add, any comment that is unrelated to the original topic of this tread will be ignored, if you what to maintain a conversation on this topic please open a new thread "events with a zero probability happen all the time"

Re: A math Problemleroy wrote:which of these 3 points do you find controversial? I find none of those controversial, I do, however, wonder why you are talking about only trillions of digits in your second point. I believe Dragan Glas is correct. However, it also seems that you agree that the real numbers are infinite. leroy wrote:yes, the fact that the real numbers are infinite... leroy wrote:So in short, the set of real numbers is infinite... Thus, back to my equation and I will make it big for you, since you seemed to have missed it the last time. X/(real numbers)(one's time)(one's memory)(y)(z).... What is wrong with that equation? Would that not be how we determine the odds of picking a number at random? Remember, we are talking about the odds. If that is not how we would calculate the odds, please show us how. (_''_) (_.._)
