I'd estimate that the spawn chance for the rare/reinforced containers are something between 0.1% and 2% per normal mission (based purely on experience of encountering them myself, there is no factual data for this afaik). Ofc it requires that the mission includes spawn locations for rare items and missionstypes/tilesets are vastly different in that regard. I don't know if the spawn chance is determined by mission instance or spawn location, but regardless only one can spawn per mission. At least I've never seen anyone show any evidence to prove otherwise.

Discontinued raids(trials) were an exception to these observations as they had a very high chance of spawning both of the rare and reinforced containers simultaneously.
