... Two different senses of 'probable'!
(1) epistemological sense (e.g., 'Given the information available, probably p.')
(2) metaphysical sense (e.g., 'Given the facts, probably p.')
Two variants of the epistemological sense (?): (a) strength of belief; (b) assessment of the reliability of information.
Metaphysical sense apparently presupposes non-determinism.
