How it works
Independent trials mean past pulls never influence future ones — 99 failures on a 1% item don't raise your 100th-pull odds. Believing otherwise is the gambler's fallacy. Total odds come from the complement rule: 1 - (1-p)^n. The curve rises with more attempts but never quite reaches 100%.
FAQ
Q. If I keep trying, am I guaranteed to get it eventually?
A. It converges toward 100% statistically, but mathematically no finite number of attempts guarantees success.
Q. Why might real results differ from this calculator?
A. This shows the pure probabilistic expectation. Real games may have pity systems layered on top — check the game's own notice.
Q. What target confidence level is recommended?
A. 90–95%+ is generally considered a safe zone — but remember a 5–10% chance of failure still remains.
