Questions about this edition
What is included?
The PDF contains 72 complete cards: 18 for General Probability, 36 for Univariate Random Variables, and 18 for Multivariate Random Variables. Each card states the formula, when it applies, its variables and parameter convention, a solution route, a check, and a common error.
Is this the same as the free formula sheet?
No. The free sheet is a four-page retrieval summary. This paid edition separates concepts and distributions into 72 cards and adds model selection, parameter discipline, support and boundary checks, and explicit error diagnosis.
Does it reproduce official problem statements?
No. The cards are independently written reference material and contain no official question wording. Exam names are used only to identify the relevant syllabus.
Does it contain all 718 worked solutions?
No. The cards are for fast recall and formula selection. The Probability Proof Manual contains the complete step-labeled solution, distractor analysis, verification record, and worked original variant for every active reference.
Which syllabus does this edition follow?
The card map follows the September 2026 Probability syllabus and covers its General Probability, Univariate Random Variables, and Multivariate Random Variables learning outcomes.
Can I print the cards?
Yes. The personalized PDF is licensed for the purchaser's own digital study and personal printing. Redistribution, resale, and public upload are not permitted.
How do refunds work for a digital download?
Report a delivery or file-opening failure, duplicate charge, or material mismatch with this description to contact@fermion.company within 14 days for correction or refund review. Change of mind and exam outcome are not refund grounds. Mandatory consumer rights remain unaffected.
