Are statements about probability universal truths? Is it possible to conceive of a universe in which a fair coin lands heads 75% and tails 25% of the time?

There are at least two possibilities you might be getting at: First, it's surely possiblle for an evenly weighted coin (even in this universe) to come up heads 75% of the time over the course of its life. Suppose I mint a coin; it comes up tails just one of the four times I flip it; and then I melt it. Second, it's conceptually possible for a universe to contain laws or supernatural agents that ensure that evenly weighted coins come up heads 75% of the time. I think it would be misleading to call evenly weighted coins "fair" in this alternative universe, however. Both these situations seem possible to me, although if they obtain only in different possible universes then it might remain a "universal truth" that evenly weighted coins land heads 50% of the time. In any case, we should recognize that coin "flipping" and "landing" only make sense where there is a reasonable amount of gravity. And for all I know there may be places in this universe where, for example, the uneven shape of evenly...
