Understanding Negative Binomial Probability
The Negative Binomial Distribution calculates the probability of observing a specific number of failures before achieving a predetermined number of successes in a series of independent Bernoulli trials. Each trial has only two outcomes: success or failure, with a constant probability of success.
This tool is useful in scenarios where you\'re interested in the number of failures that occur before a certain number of successes are reached. For example, in sales, it could represent the number of no-sales before closing a certain number of deals.
Key terms:
- r (Number of successes): The target number of successful outcomes.
- p (Probability of success): The likelihood of success in a single trial (between 0 and 1).
- k (Number of failures): The number of failures observed before achieving 'r' successes.
