If we consider a bipartite system as in EPRB experiment we get the probabilities :(adsbygoogle = window.adsbygoogle || []).push({});

p(++)=p(--)=1/4*(1-cos(theta))

p(+-)=p(-+)=1/4*(1+cos(theta))

p(+A)=p(+B)=p(-A)=p(-B)=1/2

Thus the sum of all the probabilities equals 3...

How does that come ? Is it because in fact there are only double events out of which we consider the averages of A and B sides too, thus making 3 sample set out of one experiment ?
