On strong law of large numbers for non identically distributed random variables

A new version of a strong law of large numbers for a good'' pairwise independent sequence of random variables (r.v.'s) with a small part of bad’’ dependent r.v.‘s is proposed. The main goal is to relax the assumption on the existence of the expectation for each summand: the members of an ``infrequent’’ part of the whole sequence may have moments of orders converging to zero.
