1. What is the OSRS Pet Drop Rate Formula?

The OSRS (Old School RuneScape) pet drop rate formula calculates the probability of receiving a pet after multiple attempts. It's based on the mathematical principle of calculating the probability of at least one success in multiple independent trials.

2. How Does the Calculator Work?

The calculator uses the probability formula:

\[ P = 1 - (1 - p)^k \]

Where:

\( p \) — Drop probability per attempt (0-1)
\( k \) — Number of attempts
\( P \) — Cumulative probability of getting at least one pet

Explanation: The formula calculates the probability of getting at least one pet drop after k attempts, considering each attempt is independent.

3. Importance of Drop Rate Calculation

Details: Understanding drop probabilities helps players estimate how many attempts they might need to obtain rare pets, set realistic goals, and manage expectations when grinding for rare drops in OSRS.

4. Using the Calculator

Tips: Enter the drop probability (p) as a decimal between 0 and 1 (e.g., 0.0001 for 1/10,000 chance) and the number of attempts (k) as a positive integer. Both values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: Why use this formula instead of simply multiplying p × k?
A: Multiplying p × k gives the expected value but doesn't accurately represent the probability of getting at least one drop. This formula accounts for the compounding probability over multiple attempts.

Q2: What's considered a "good" drop rate in OSRS?
A: Pet drop rates vary greatly in OSRS, ranging from 1/100 to 1/10,000 or even rarer. Generally, rates below 1/1000 are considered rare.

Q3: Does killing multiple monsters increase my chance per kill?
A: No, each kill is an independent event with the same probability. However, more kills increase your overall chance of getting at least one pet over all attempts.

Q4: Are there any tricks to increase pet drop rates?
A: No, pet drop rates are fixed per activity and cannot be increased except through specific game mechanics like certain equipment or boosts that explicitly state they affect drop rates.

Q5: How accurate is this calculator for actual OSRS gameplay?
A: This calculator provides the mathematical probability based on the input values. Actual in-game results may vary due to the random nature of probability, but over large numbers of attempts, results should approach the calculated probability.
