The trivium is a just a structure of teaching. It does not apply well to luck or randomness.
It is a toolbox for analysing what happened, after it happened.

The most important thing about the trivium is comparing it to modern govern-cement schooling.
If you learn by method of the trivium, you start by reading all of the great works.
Then you are taught how to synthesize, put together the different thoughts.
Then you are taught how to express these thoughts to other is a convincing manner.

As opposed to modern govern-cement schools which start with rhetoric.
Or, they teach you what to think, not how to think.
