A 78-Card Tarot Deck Checklist: Missing, Duplicate and Bonus Cards
Count each required identity, then account separately for duplicates, edition-specific extras and unresolved labels.

Tarot Draw Probability: Card Counts, Shared Cards and Repeat Runs
Six guides help you check the card pool, define the draw rules and choose the event you actually want to count. A model calculation does not establish a card’s cause, an app’s fairness or a future event.
Check the pool and identity labels
A physical inventory determines the inputs; it does not certify random selection.
Count a category or cover all four suits
One group count and simultaneous coverage of four groups are different events.
Major Arcana Probability in a Three-Card Spread: Exact Odds
Count zero, one, two or three Majors under explicit uniform without-replacement rules.
All Four Tarot Suits in One Spread: Exact Model Probabilities
In a uniform four-card draw without replacement from the 78-card reference, all four Minor suits appear with probability 2.693166%. With five cards it is 8.734594%. Drawing only from the 56 Minors is a different experiment. Count Major cards separately instead of assigning them a suit.
Choose the repeat, spread or window question
Next matches, reset-spread intersections and consecutive runs need their own procedure and event.
Drawing the Same Tarot Card Repeatedly: Probability and Journaling
Distinguish next matches, named-card events, whole-window matches and any identity repeat.
Shared Cards Between Two Tarot Spreads: Reset, Overlap and Order
Two independently reset three-card spreads from a uniform 78-identity pool share at least one identity with probability 11.240076%. The same three names in any order and the same three assigned positions are smaller, different events. State the reset rule before comparing them.
Consecutive Tarot Card Repeats: A Run Within a Longer Record
Under a uniform 78-identity independent replacement model, the chance of a length-three run somewhere in seven picks is 0.081332%. This differs from all seven matching or any identity repeating. Overlapping candidate windows require a count that avoids double-counting.
Define the procedure before attaching a number
Record the available identities, replacement within a draw, reset between spreads and the event window. Uniformity and independence are model assumptions unless established for the actual selection process.
Use the complete worked counts and cases to understand the model. Keep an observation separate from an optional creative association, and use real information for consequential decisions.
