The truth-functions can be ordered in series.

That is the foundation of the theory of probability.

5.101

5.11 If the truth-grounds which are common to a number of propositions are all also truth-grounds of some one proposition,
we say that the truth of this proposition follows from the truth of those propositions.

5.12 * (4)*
In particular the truth of a proposition "p" follows from that of a proposition "q",
if all the truth-grounds of the second are truth-grounds of the first.

5.13 * (6)*
That the truth of one proposition follows from the truth of other propositions, we perceive from the structure of the propositions.

5.14 * (3)*
If a proposition follows from another, then the latter says more than the former, the former less than the latter.
