NEGBINOM.DIST

The NEGBINOM.DIST function in Google Sheets is a statistical function that calculates the probability of achieving a specific number of failures before a target number of successes is reached, using a negative binomial distribution. This function is useful in various scenarios where you need to analyze and interpret data based on a negative binomial distribution.

Function Syntax and Parameters

Syntax: NEGBINOM.DIST(num_failures, num_successes, prob_success)

Parameters:

• num_failures: The number of failures before the target number of successes is reached.
• num_successes: The target number of successes.
• prob_success: The probability of success in each trial.

Step-by-Step Tutorial

1. Calculating NEGBINOM.DIST:
   • Example: =NEGBINOM.DIST(5, 10, 0.3)
   • Result: The probability of observing 5 failures before achieving 10 successes with a success probability of 0.3.

Use Cases and Scenarios

1. Quality Control: Calculate the probability of encountering a certain number of defects before finding a specific number of non-defective items.
2. Product Development: Assess the probability of observing a certain number of failed prototypes before achieving a desired number of successful prototypes.
3. Risk Analysis: Analyze the likelihood of experiencing a certain number of unsuccessful attempts before achieving a defined number of successful outcomes.
