Not at all. But some people misuse it. I just happened to notice similarities in the use of prior probabilities.
Handing you a homemade deck of cards and asking you to guess if the ace of spades is in it is "maliciously altering the rules"? LOL, OK.
I see. If I choose semantic accuracy, you will simply declare yourself "right", take your marbles, and go home, eh?
You have yet to address the substantive problem with your quibble-cook; will this post be any different?
Perhaps the thread should end on this note. As I said, it's not my job to educate you guys on probability.

Nor is it within your range of talents, AFAICT.
I didn't assign any prior probabilities when I did my calculation.
A prior probability is what you assign to a hypothesis before you evaluate the evidence. I have not assigned a prior probability to either alien life or ESP.
You proved it yourself:
Can a bachelor be a married man? No.
Can a bachelor land as a married man? Yes.
Can a two-headed coin be a two-tailed coin? No.
Can a two-headed coin land as a two-tailed coin? Yes
Do you see now? If not, I don't know how else to explain it.
... Do you think I have an infinite amount of time to talk ...
Remarkably silly, and a lot of work to avoid admitting your own error.
The bachelor ceases to exist in midair; he is, as you put it, changed into "something entirely else"; what lands is not a "bachelor", but a "married man".
Your "two-headed coin" ceases to exist when the "magic" happens (when the crowd claps its hands); it is, as you put it. changed into "something entirely else"; what lands is not a "two-headed coin", but a coin with at least one tail.
Do you "see it now", Fud? You are making an indefensible claim about an untenable position. It doesn't matter how you pretend to "explain" it. A "two-headed coin" cannot land showing "tails"; a coin that has at least one "tails" to show is not (by definition) a "two-headed coin".
Q: how many "tails" does a "two-headed coin" have?
A: Zero (not "almost zero"; zero)
No matter how widely you wave your hands, Fud.

Take my marbles and go home? Really? Have I not bent over backwards trying to explain this in many different ways? Do you think I have an infinite amount of time to talk about some logically possible/impossible scenario?
I have explained why you are wrong, and given plenty of examples that show the flaw in your reasoning: Two-headed coins can "land" tails in the same way a bachelor can "land" as a married man (which you've already admitted can happen).
The married man is still the same person.
The coin is still the same coin.
Both were changed during a time interval in the scenario.
Maybe you need to draw a cartoon version![]()
Apparently, it is, in fact, important to you. WHy hlse would you keep ignoring the reality that your construction is indefensible?
A "two-headed coin" cannot land showing "tails".
A coin that shows "tails" cannot be a two-headed coin.
Even if (pace technology) you were to posit a coin with holographic faces that could be programmed to change in midair; a "coin with multiple programmable faces" is not a "two-headed coin".
No matter how loudly you declare yourself "right", Fud.
What rhetorical advantage do you think falsehood boons you?
Go back and read: The bachelor, married in midair, lands as a married man, no longer a bachelor. The "two-headed coin", magically changed in midair, lands as "a coin with at least one tail to show", no longer a "two-headed coin".
That is not the "admission" you claim I made.
No matter what you "declare", Fud.
He is not, however, "the same"; no longer a "bachelor"; he is "married".
Just in case you are actually paying attention, "married" =/= "bachelor".
it is not, however, "the same"; no longer a "two-headed coin", it has at least one "tail" to show.
Just in case you are actually paying attention, "two-headed coin" =/= "coin with at least one 'tails' to show".
And when you beat it into a ploughshare, it is, in fact, no longer a sword, Fud. In fact, you would be hard-pressed to beat it back into a decent sword...
But by all means, do enjoy your "declarations". Reality will still be here.
I would agree, on the face of it, but you're sneaking in some prior background knowledge (that standard decks don't have a 42 of spades), which is why I changed it to what I did. But even without changing it, you're still not on solid ground. If there's not an ace in the deck than the odds of a 42 of spades coming up are higher than an ace appearing.
So I don't think you can conclude that an ace appearing is more likely than a 42 of spades. In order to do so, you would have to look at a face down card and assign some kind of probability to it being an ace.
