Abstract
I apply the distinctions between the probability of a conditional, and a conditional with a probabilistic consequent, to quantum theory. I concentrate on an application hardly studied in the literature: namely, the case where the antecedent of the conditional states which quantity is measured, and the consequent states which value the quantity has. I show how we can construe quantum theory as providing propositions of these kinds, both for intrinsic possessed values, and for measurement results. I also show that most construals satisfy a plausible constraint requiring a kind of independence between which quantity is measured and what the value or result is.
