Probability logic is an important foundation for uncertainty reasoning. However, there is a lot more to do to make it perfect. Universal logics is a new flexible logic system established in the study of various nondeterministic problems. It is an abstraction for building concrete logic systems. Theoretically, probability logic is a special example of universal logics. In this paper, several classical models are analyzed, problems in these models are pointed out, and new methods to solve them based on universal logics are presented.
