Abstract
One of the Bell's assumptions in the original derivation of his inequalities was the
hypothesis of locality, i.e., the absence of the in
uence of two remote measuring instruments
on one another. That is why violations of these inequalities observed in experiments are often
interpreted as a manifestation of the nonlocal nature of quantum mechanics, or a refutation
of a local realism. It is well known that the Bell's inequality was derived in its traditional
form, without resorting to the hypothesis of locality and without the introduction of hidden
variables, the only assumption being that the probability distributions are nonnegative. This
can therefore be regarded as a rigorous proof that the hypothesis of locality and the hypothesis
of existence of the hidden variables not relevant to violations of Bell's inequalities. The physical
meaning of the obtained results is examined. Physical nature of the violation of the Bell
inequalities is explained under new EPR-B nonlocality postulate.We show that the correlations
of the observables involved in the Bohm{Bell type experiments can be expressed as correlations
of classical random variables. The revisited Bell type inequality in canonical notatons reads
<AB>+<A′B>+<AB′>-<A′B′>≤6.
