Expected to occur or succeed.

Etymology
From testing came the idea of something provable and therefore credible. Probable came to describe what has more evidence for it than against it, without requiring certainty.
In context
all such expectations are only probable thus we have not to seek for a proof that they must be fulfilled but only for some reason in favor of the view that they are likely to be fulfilled
