  This argument is valid. If the premises are true, we have a direct argument for RCT. We have no direct response to the objections raised in  §§4–5,  but somehow, if this argument succeeds, those objections must miss the point. The premises have some initial plausibility (though P2 is dubious: surely a properly indeterministic process could produce any sequence of outcomes whatsoever, including many non-random sequences? We discuss this further in  §7.2).  The thesis that indeterminism is necessary and sufficient for chance has long been a popular claim. And randomness and indeterminism also seem to have a close connection. But to evaluate them, we will need to be more precise than we have been about determinism.
