Figure 5

Illustration of how the posterior probability depends on the three parameters of Bayes' rule. Each plot shows two curves for the posterior probability as a function of one of the three parameters (with the remaining two parameters held constant) chosen from among one of two sets of values for(Pr(A), Pr(F|A), $Pr(F|\overline{A})$), either (0.3, 0.95, 0.05) or (0.1, 0.7, 0.15).
