Original question and givens

The experiment is one draw from explicitly labelled cards with elementary outcomes label 1, label 2. At this observation scale the candidate sample space is S={label 1, label 2}. Is it complete?

  • G001 — The experiment is one draw from explicitly labelled cards with elementary outcomes label 1, label 2. At this observation scale the candidate sample space is S={label 1, label 2}. Is it complete?

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.

Step-by-step derivation

S001 · implies

Before

source roles = [qf-finite-sample-space-completeness, [expected_outcomes, experiment, listed_outcomes, mode, observation_scale]]

After

derived = [sample, null, null]

Conditions: none

Use THIS bank’s actual fields,operation/domain and types.BASE retains permissible extra metadata.Do not import LDL SAFE/set limits or a different bank’s deduplication rules.

Step identifiers and dependencies

Rule: R70_SOURCE_bank_specific_interface · Uses: G001

S002 · implies

Before

source roles = [one reading of the declared labelled cards label 1、label 2, one declared finite trial, [label 1, label 2], [label 1, label 2]]

After

derived = [completeness only]

Conditions: none

A is GIVEN as the COMPLETE elementary-outcome list at the declared observation scale.Check whether B is exactly A;do not infer the universe from partial observations or assign equal likelihood/probabilities.

Step identifiers and dependencies

Rule: Sample_GIVEN_complete_elementary_outcomes_at_declared_scale · Uses: G001, S001

S003 · implies

Before

source roles = [label 1, [label 1, label 2]]

After

derived = [Yes]

Conditions: none

Check EACH required outcome for inclusion;all listed outcomes being legal does not rule out a missing one.

Step identifiers and dependencies

Rule: Sample_EACH_expected_outcome_is_listed · Uses: G001, S002

S004 · implies

Before

source roles = [label 2, [label 1, label 2]]

After

derived = [Yes]

Conditions: none

Check EACH required outcome for inclusion;all listed outcomes being legal does not rule out a missing one.

Step identifiers and dependencies

Rule: Sample_EACH_expected_outcome_is_listed · Uses: G001, S003

S005 · implies

Before

source roles = [label 1, [label 1, label 2]]

After

derived = [Yes]

Conditions: none

Check EACH listed outcome against the GIVEN universe;absence of omissions does not rule out impossible extras.

Step identifiers and dependencies

Rule: Sample_EACH_listed_outcome_is_possible · Uses: G001, S004

S006 · implies

Before

source roles = [label 2, [label 1, label 2]]

After

derived = [Yes]

Conditions: none

Check EACH listed outcome against the GIVEN universe;absence of omissions does not rule out impossible extras.

Step identifiers and dependencies

Rule: Sample_EACH_listed_outcome_is_possible · Uses: G001, S005

S007 · implies

Before

source roles = [[], [], complete]

After

derived = [Yes]

Conditions: none

Completeness requires BOTH inclusions.If both omissions and extras occur,the answer remains No;the source mode prioritizes omissions.Check mode only AFTER set comparison.

Step identifiers and dependencies

Rule: Sample_BOTH_inclusions_and_postderived_mode · Uses: G001, S006

Result

Yes

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.

This question review and source binding

Review date: 2026-10-26

Original questions, answers, step expressions, numeric ASTs and historical records are retained. Source candidate labels remain historical and are not overwritten as formal proof.
