  A review of the tomographic-probability representation of classical and
quantum states is presented. The tomographic entropies and entropic uncertainty
relations are discussed in connection with ambiguities in the interpretation of
the state tomograms which are considered either as a set of the probability
distributions of random variables depending on extra parameters or as a single
joint probability distribution of these random variables and random parameters
with specific properties of the marginals. Examples of optical tomograms of
photon states, symplectic tomograms, and unitary spin tomograms of qudits are
given. A new universal integral inequality for generic wave function is
obtained on the base of tomographic entropic uncertainty relations.
