Well, if determinism means "if you are given the exact starting conditions of a system, you can tell me exactly how it will evolve with time," then modern Physics is emptily deterministic - since the Uncertainty Principle prohibits you from ever knowing the exact starting conditions of any system.

When someone claims A => B, it can be true either because there exist cases in which A is true, and in those cases, B is true also, or because A is never true. It is true to say: "all wabajahooies are yellow and slimy," if there are no wabajahooies in existence. Otherwise stated, every set contains the empty set.

As for "Indeterminism," I may have misunderstood, but what's the difference between having events that are not predetermined and saying that those events are random?
