OLD and L&S give it classically in Cicero, mind you, in a sense of probability.Apud Ciceronem obiter secundum OLD et L&S dictionaria id probabilatis sensu reperitur.Post scriptum
Strictly speaking, "without doubt" isn't "probably", of course, but it doesn't much matter, I agree.Nec strictim "probabiliter" significat "sine dubio". Quid autem refert, tecum concurro.
I'm writing in Latin hoping for correction, and not because I'm confident in how I express myself. Latinè scribo ut ab omnibus corrigar, non quod confidenter me exprimam.
