These are Topps’ official published odds for 25 26 Bowman U Best Basketball (Standard). A parallel’s rate is for any card in that parallel — a specific player is far rarer. The model treats each pack as an independent draw at the stated rate; real collation clusters hits.
How the Odds Are Calculated
Topps prints the pull rate of every parallel as “1 in N packs.” The calculator turns that into the numbers people actually ask for:
- Chance of ≥1 — the probability at least one of your packs has that card,
1 − (1 − 1/N)^packs. - Expected — the average number across your packs,
packs / N. - Packs to a 50 / 90 / 95% shot — solving the same formula backwards,
ln(1 − t) / ln(1 − 1/N).
Two honest caveats. A parallel’s odds are for any card in that parallel — a specific player is much rarer. And the model assumes each pack is an independent draw at the stated rate; real Topps collation can cluster or space out hits, so a live box can over- or under-shoot.
