Understanding Binomial Distribution

A binomial distribution describes the probability of achieving a specific number of successes in a fixed number of independent trials, where each trial has the same probability of success.

When to Use Binomial Distribution

  • Fixed number of trials
  • Each trial is independent
  • Only two possible outcomes (success/failure)
  • Constant probability of success

Common Applications

Binomial distributions are used in various fields:

  • Quality control in manufacturing
  • Medical trial success rates
  • Election polling and forecasting
  • Sports statistics and game outcomes
