I'd say that these voters can't even determine what the mean *is*. The
mean is based on utility estimates, which are made on the assumption
that a candidate's estimated utility corresponds to the voter's happiness
with the result when this candidate is elected. If the voter can't
estimate this independently, he has to use a different strategy.

This would affect the utilities of the choices.

What you should ask instead is "Given X free chances, would you rather
have a fifty-percent chance of 0.17 utility or a one-percent chance of
10 utility?"

The default prize is 0 utility. You should assume that the special value
(if any) of having some utility rather than no utility has already been
accounted for. Otherwise, I don't see what the 0.17 and 10 figures would
be based on, or even what this question is asking.
