When I toss a fair coin, I am epistemically indifferent about the outcome
of the toss.  Do I believe in one outcome or the other?  No, I commit myself
to neither alternative.  So, Bel(Jim,Prob(heads)=.5) and
Bel(Jim,Prob(tails)=.5)
I believed that the Oilers would win Game 5 of the Cup Finals.  I could
construct an argument to lend credence to my belief.  I was by no means
certain that they would win (I say in hindsight), but I thought they stood
a pretty good chance.  Let's assign a measure of probability, say .75.
So, Bel(Jim,Prob(win)=.75) and Bel(Jim,Prob(lose)=.25).  I can't say I
entertained the latter belief a great deal (until the third period, but
by then I had changed my assessment of probability), and one might wish
to argue that I had no such belief at all.  But I definitely had the former
belief in mind.
So, while it is the case that I believed that the Oilers would win the game,
I would not admit to Bel(Jim,Prob(win)=1.0), and hence I'd never assert
that it's true that the Oilers were going to win Game 5.  With regard to
more reliable empirical observations/predictions, I'd assign much higher
probabilities, and would likely reach a point whereat the negation of my
belief would never be entertained at all.  But, being a skeptic, upon
being asked whether a particular proposition was true, I'd be reluctant
to agree even to the most blatantly obvious claims.
