 This upper bound on the uncertainty of the conclusion is rather disappointing, and it exposes the main weakness of Theorem 2. One of the reasons why the upper bound is so high, is that to compute it we took into account the premise \(s\), which has a rather high uncertainty (\(4/11\)). However, this premise is irrelevant, in the sense that the conclusion already follows from the other three premises. Hence we can regard \(p\wedge (q\vee r)\) not only as the conclusion of the valid argument \(A\), but also as the conclusion of the (equally valid) argument \(A'\), which has premises \(p,q,r\). In the latter case Theorem 2 yields an upper bound of \(1/11 + 2/11 + 2/11 = 5/11\), which is already much lower.
