The philosophical distinction between deterministic and random is not that clear as the randomness itself could be determined by a hidden process, as in "god is rolling the dices". Likewise the distinction between deterministic and predictable is not that clear either, as you can have a fully deterministic process that is not replicable or predictable. (Think of chaotic systems) In the end I think that the question of free will is not a scientific one but a moral one, as it is from the basis of free will that we can derive concepts such as personal responsibility.
