Abstract: A new method based on condition probability is proposed to compute degree of support about probabilistic entailment in R. Haenni’s probabilistic argumentation systems, and application of this proposed method to detect faulty components in a logic circuit is introduced.

Key words: probabilistic argumentation systems, condition probability, degree of support about probabilistic entailment
