This is surely 1 in 4. 1 out of 4 times your message is intercepted
and reconstituted in Hell. So 1 in 4 times you go to Hell.
b) with a non-destructive eavesdropping?
1 in 4 times your message is intercepted, and on that occasion there
is a 50-50 chance to find yourself in Hell. So there is a 1 in 4
chance of interception, and half that of ending in Hell, so 1 in 8.
(This is assuming that your are digitally emulable, of course.
Otherwise teleportation will destroy you, so the chances are 0 in
each case.)
I can see that, but I'm not sure there isn't another split of
probabilities/events when the message is intercepted and the
branches split into "eavesdropping destructive" and "non-
destructive" respectively.
There where really two questions. One in which we are certain that the
eavesdropping is destructive, in which case the probability is just
the probability of the eavesdropping = 1/4.
Same for half the reconstitutions following non-destructive
eavesdropping landing me in Hell and half on Mars, which you already
pointed out. In this case, high school probability stuff still rings
bells (even if they might be out-of-tune here, lol) like so:
Are you OK with Liz?
The event "eavesdropping" and "be split", in the non-destructive case,
are independent, so the probabilities are multiplied 1/4 * 1/2 = 1/8.
Any question PGC, people, John C, John M., anyone?
