Which type of analysis is done when all facts are available?

Probabilistic analysis is used precisely when all facts are NOT available, relying on statistical inference and likelihood to reach conclusions.

Deterministic analysis uses a full and known set of inputs to produce a reproducible, certain outcome with no ambiguity. In cybersecurity and threat intelligence, this means all variables are accounted for and the result is definitive rather than an estimated likelihood. This contrasts with probabilistic approaches that assign confidence levels because some facts are missing or uncertain.

Static analysis refers to examining code or data at rest without executing it - it describes the method of examination, not the completeness of available facts.

Dynamic analysis involves observing system or code behavior during active execution, which describes the analysis environment rather than the availability of facts.
