Question 27690: Outside-Scope Inputs Are Not General Strong-Law Counterexamples

Original question and givens

Use mode=finite_prefix, complete model={"values":[2,3],"probabilities":[[1,4],[3,4]],"observations":[2,3,2]}. Give (mode, observations, common_mean, infinite_process_or_limit_proof_claim, boundary).

• G001 — Use mode=finite_prefix, complete model={"values":[2,3],"probabilities":[[1,4],[3,4]],"observations":[2,3,2]}. Give (mode, observations, common_mean, infinite_process_or_limit_proof_claim, boundary).

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
