@kennethamy,
I hesitate to repeat a point which I have already made in another thread, but part of the confusion arises from the fact that we instinctively like to think in terms like 'cause' and 'effect' (and 'determinism') which are borrowed from classical metaphysics and, except as a kind of conversational shorthand, have no meaning or application in modern science (least of all quantum mechanics).
It was David Hume in the 18th Century who first pointed out, I think, that no-one has ever seen a 'cause'. When we say that 'A causes B', we really mean that in every case where we observe A, we observe that B follows. We rationalise it by saying that A 'causes' B.
To go further and postulate 'cause' as some kind of mysterious third entity, perhaps a kind of logical necessity, perhaps a physical 'action at a distance', not immediately perceptible, is unwarranted; an Aristotelian hangover. It is merely a question of correlation. In science there are NO 'causes', only probabilities ranging between 0 and 1.
