Pack-Ripping Odds Explained
How to interpret per-opening probabilities and independence.
Single opening
If a stated chance is 1 in 100, the probability per independent opening is 1%. It does not guarantee a win within 100 attempts.
Repeated openings
For independent openings with chance p, probability of at least one success in n attempts is 1 − (1 − p)^n. Real promotions may have changing odds or dependent inventory.
