Calvinists, Thomists, and Molinists all agree that the future is written (while disagreeing on how God took our free will into account in “writing” it).
Yes there is, but it’s an “undiscovered country.”
It follows that if (as seems to be the case) the digits of π are “random,” then they are so in a similar sense to the digits produced by dice. The digits in both cases are determined and known by God, but only a finite number of them are known to us at any given point in time. Concerning the digits as yet unknown to us, we can only guess according to the well-tested laws of probability.
A π pie. Are the digits of π random? (Search π here)
It also follows that it makes sense to pray for good academic results, even if they are sitting in front of one in an unopened envelope (anything for which we have not yet reached the point of certainty can be considered “random”). Indeed, there is even something to be said for the (probably apocryphal) child who came home after a test and prayed that London would turn out to be the capital of France.
For me, the capital of France is a certainty. For others, it may still be in the realm of probability.
