### How can one evaluate the plausibility of an eternal object?

Probability of something existing ,as it is ,forever is zero(not undefined). Probability of an improbable event is non zero, no matter how small.

### Is Arithmetic more Extensional than Probability?

In set theory, the axiom of extensionality states that two sets are equal if and only if they contain the same elements. Since an event is a set of outcomes, the external properties are reduced to ...

### Conceptual difference between probability vs percentages

All probabilities are frame-dependent. If your study says "People with gene Z have a 50% of developing disease Y", then the frame is merely 'people with gene Z' with no other qualifications. ...

### Conceptual difference between probability vs percentages

There is a saying : Lies, Damned Lies and Statistics. What you describe as "relate to" is correlation. Correlation is a relationship, an association between two variables. However, seeing ...

### Is probability a concept derived from the wavefunction? Since the p.d.f. is found by finding the modulus of the wave function in Q.M

Probability is most definitely not a concept derived from the wave function. Quantum theory is a relatively recent development; the idea of probability pre-dates it by centuries. There are countless ...

### Is probability a concept derived from the wavefunction? Since the p.d.f. is found by finding the modulus of the wave function in Q.M

In qm the position (until measurement) "is not decided". It's not that it "is not known" in the sense that we do not know where exactly it is. This situation cannot be described in ...

### Is probability a concept derived from the wavefunction? Since the p.d.f. is found by finding the modulus of the wave function in Q.M

Yes, in quantum mechanics the value of the probability density derives from the wave-function. As you write, the squared modulus of the wave-function equals the probability density. That the wave-...

### Is a probability operator on propositions symmetrical?

First phrase: yes, this is just common language expressing the rule of subtraction: P(X) = 1-P(X') Second phrase: no. If it is 50% probable that one moose randomly selected out of all moose is green, ...

### Does the law of large numbers explain why quantum mechanics leads to statistical regularities?

I have pondered this, but I'm no scientist. This might be related to the question: "where does the universe end on either macro or micro scale?". But at any scale, any physical phenomenon ...

### Does the law of large numbers explain why quantum mechanics leads to statistical regularities?

Perhaps you might be reading too much into the meaning of the word probabilistic when you ask why does the world have to be probabilistic instead of chaotic. There is a sense in which you can't escape ...

### Does the law of large numbers explain why quantum mechanics leads to statistical regularities?

The “law of large numbers is a theorem that describes the result of performing the same experiment a large number of times. According to the law, the average of the results obtained from a large ...
