 In other words, if we know the probabilities of the argument’s premises, then we can calculate the exact probability of its conclusion, and thus provide a complete answer to the question of probability preservation for this particular argument (for example, if \(P(p \vee q) = 6/7\) and \(P(p\to q) = 5/7\), then \(P(q) = 4/7\)). In general, however, it will not be possible to calculate the exact probability of the conclusion, given the probabilities of the premises; rather, the best we can hope for is a (tight) upper and/or lower bound for the conclusion’s probability. We will now discuss Adams’ (1998) methods to compute such bounds.
