In earlier work, we presented a process algebra, PACSR, that uses resource failures to capture probabilistic behavior in reactive systems. In this paper, we explore the effects of resource failures in the situation where resources may be hidden from the environment. For this purpose, we introduce a subset of PACSR, called "PACSR-lite," that allows us to isolate the issues surrounding resource hiding, and we provide a sound and complete axiomatization of strong bisimulation for this fragment.
