Section 3
Question 24
Emil-Kunkin on May 7, 2023
I'm not sure how D would strengthen. I think for D to improve the argument we would need to know more about the proportion of total letters that were deemed important, and we cannot assume that. As of now all we know if D is true is that at a max, there were 40k important letters, and we have over 40k seals. We don't actually know how many important letters there were, we only know that the number is fewer than 40k. The actual number may be 39999, or 3.
