ToA Drop Probability Formula:
| From: | To: |
The ToA (Tombs of Amascut) Drop Probability Formula calculates the probability of obtaining at least one drop after multiple attempts in Old School RuneScape. It provides a mathematical approach to understanding drop rates over multiple runs.
The calculator uses the probability formula:
Where:
Explanation: The formula calculates the complement of the probability of not getting the drop in all attempts, giving the probability of getting at least one drop.
Details: Understanding drop probabilities helps players estimate the number of attempts needed for desired items, manage expectations, and plan their in-game activities more effectively.
Tips: Enter the drop probability per attempt (between 0 and 1) and the number of attempts (positive integer). All values must be valid.
Q1: What does this probability represent?
A: It represents the probability of getting at least one drop after k attempts, not the probability of getting exactly one drop.
Q2: How accurate is this calculation?
A: The calculation is mathematically precise based on the provided probabilities and assumes independent attempts with constant drop rates.
Q3: Can I use this for other drop calculations?
A: Yes, this formula applies to any scenario with independent attempts and constant probability, not just ToA drops.
Q4: What if I want to calculate multiple drops?
A: This formula calculates the probability of at least one drop. For multiple drops, you would need to use binomial probability calculations.
Q5: Why do I sometimes not get drops even with high probability?
A: Probability indicates likelihood, not guarantee. Even with 99% probability, there's still a 1% chance of not getting the drop.
