Well, it's not really a matter of whether you want to believe stuff's random or not. Bell's theorem indicates that it is. You could say it "sounds like giving up" to accept the law of momentum conservation instead of trying to build a reactionless drive, but the universe won't give you any points for doggedly forging on. :-)

But if there's a way to predict it, then you can write down a list of numbers based on that prediction. Being able to write down a list of numbers which then turn out to be correct is the minimal requirement for determinism. If you can't do that, you can't determine the outcome in any way.
And, by the way, a list of numbers is a perfectly good scientific theory of dice-rolling. It's definite and it's verifiable; just look at every dice roll over eternity and see if they check out. Sure, it's not a very pretty theory, but it's still valid. And when you get right down to it, every theory that scientists construct is simply a set of instructions for how to figure out that list of numbers. The theory, in the form of words and equations, doesn't contain any more information than the same theory in the form of a number list; it's just a lot shorter and prettier.
