Boole and Bell inequality

We discuss the relation between Bell’s and Boole’s inequality. We apply both to the analysis of measurement results in idealized Einstein‐Podolsky‐Rosen‐Bohm experiments. We present a local realist model that violates Bell’s and Boole’s inequality due to the absence of Boole’s one‐to‐one correspondence between the two‐valued variables of the mathematical description and the two‐valued measurement results.
