If you pick a random number from an infinite set of numbers an infinite number of times, will you ever pick a repeated number?

>> No.5004639

maybe

>> No.5004643

you can't pick a random number out of infinity

>> No.5004647

no

>> No.5004650

yeah, you would. an infinite number of times.

im not sure you can really answer that, because 'infinity' is not a defined value... just a really big one. so how can you say anything about the probability when you don't know how many picks you are making?

the probability is still zero.

>infinite set of numbers
What kind of numbers? What cardinality?

>> No.5004691

>>5004643
you could if you used a non-uniform distribution

the probability is zero but it can still happen

1 divided by infinity = 0

Being infinitely long, do irrational numbers eventually repeat themselves? (I'm aware this would make them rational.)

>> No.5004738

>>5004709
that's not infinite picks from an infinite set though, its infinite picks from a set of 10

>> No.5004743

Infinity is not a number, it is a concept.

>> No.5004745

>>5004709
No.

>> No.5004754

well, if it were an infinite set of the number 7, you would get 7 every time.

Halting Problem.. Check Mate Kalam's ass.

Infinity doesn't exist in reality

>>5006339
no computer will work for ever - so halting problem is no proof of infinity

what is "Check Mate Kalam's ass"?

lim t->+infinity (1/t) = 0
Is the probability of choosing any one number.

lim t->+infinity (1/t * 1/t) = 0
Is the probability of choosing that number again

lim t->+infinity t(1/t *1/t)
= lim t->+infinity (1/t) = 0

No, you would not be able to repeat that number.
