That is neither right nor wrong because it is not clear what
"the probability" refers to; the probability of *who* seeing spin up?
Oh, You said us that in the MWI there were no problem as the copies
cannot met, and so the use of probability makes sense in QM. OK you
did change your mind, and I guess this is to hide the fact that your
argument against the FPI and Chris Peck's argument would contradict
each other. It looks a bit opportunistic to me, and it annihilates
your previews post on the subject.
What I am claiming is that if the MWI is correct and if Quentin
Anciaux performs a spin measurement on a electron then Quentin
Anciaux will see spin up with 100% probability and Quentin Anciaux
will see spin down with 100% probability.
In the description of the wave, yes, a typical 3-1 view. But n QM we
use that to evaluate outcomes of future measurement, and we get
probabilities.
I am also claiming that if Quentin Anciaux measures the spin of a
electron and I say "I bet Quentin Anciaux got spin up" I will win
the bet 50% of the time. Again assuming that the MWI is correct.
You get only probability 100% if you include yourself in the wave, by
what you say above, or you get solipsisme, as you allow probabilities,
but only for you, which is indeed a way to confuse the 3p and the 1p.

so you lied to us for years saying the contrary,
And likewise the probability of Quentin Anciaux fucking a horse
is 100% and the probability of Quentin Anciaux fucking a mule is
100%; but if I say "I bet it was a mule not a horse that Quentin
Anciaux fucked" I will win my bet 50% of the time.
