We derive non-local bivalued probabilities of click or no-click outcomes—corresponding respectively to detection or no-detection of the particles—where each of the Einstein–Podolsky–Rosen–Bohm (EPRB) pair of particles is observed in only one of the (2s + 1) possible spin projection channels. In the case of observations in maximum spin down channels, our results coincide exactly with those given by Wódkiewicz 3. We analyse the nature of correlation between the click–no-click results with the help of non-local conditional probabilities and information entropies. We observe that the violation of co-planar BC inequalities is essentially due to stronger correlations between the click–no-click outcomes in the spin projection channels |λa| = |λb|. This observation is also supported by spin transmission Bell inequalitites.
