Drop Probability Equation:
| From: | To: |
The Nex Drop Calculator estimates the probability of receiving a drop from Nex in Old School RuneScape based on the drop probability per attempt and the number of attempts made.
The calculator uses the probability equation:
Where:
Explanation: The equation calculates the probability of getting at least one drop after k attempts, considering the independent probability p for each attempt.
Details: Understanding drop probabilities helps players estimate the number of attempts needed for specific items, plan their gameplay strategy, and set realistic expectations for rare drops.
Tips: Enter the drop probability per attempt (typically a small decimal value) and the number of attempts. Both values must be valid (0 ≤ p ≤ 1, k ≥ 1).
Q1: What is a typical drop probability for Nex?
A: Drop probabilities vary by item, with rare drops typically having probabilities ranging from 1/100 to 1/1000 or lower per kill.
Q2: Does killing Nex in a group affect drop probabilities?
A: In OSRS, drop mechanics typically assign drops to individual players based on their contribution, with each player having their own independent chance at drops.
Q3: Are drop probabilities affected by luck or previous attempts?
A: No, each attempt is independent in OSRS. Previous kills do not affect future drop chances (no "bad luck protection").
Q4: How accurate are the published drop rates?
A: Jagex occasionally publishes official drop rates, but players often estimate probabilities through large-scale data collection and statistical analysis.
Q5: Can I use this calculator for other bosses?
A: Yes, the probability formula works for any independent drop chance system, though you'll need the specific drop probability for each boss and item.
