For satisfying SoullessAutomaton's curiosity I think phrasing it differently would have been better: which one would you bet (say, $100) if you had to do and could only pick one? (Assuming that both questions would get truthfully answered immediately after making the bet. It's just so that you wouldn't pick one of these just because the question seems more interesting.)
This is a trivial transformation that I don't see how could change the interpretation of the question.

Brain damage patients with anosognosia are incapable of considering, noticing, admitting, or realizing even after being argued with, that their left arm, left leg, or left side of the body, is paralyzed. Again I'll quote Yvain's summary:
A brief search didn't turn up a base-rate frequency in the population for left-arm paralysis with anosognosia, but let's say the base rate is 1 in 10,000,000 individuals (so around 670 individuals worldwide).
Supposing this to be the prior, what is your estimated probability that your left arm is currently paralyzed?
Added: This interests me because it seems to be a special case of the same general issue discussed in The Modesty Argument and Robin's reply Sleepy Fools - when pathological minds roughly similar to yours update based on fabricated evidence to conclude they are not pathological, under what circumstances can you update on different-seeming evidence to conclude that you are not pathological?
