Probability distributions are mathematical models that help us understand the likelihood of an event occurring. Common distributions include normal, binomial, Poisson, exponential, and Chi-squared. To understand these distributions, it is important to understand the equations behind them and how to use them to solve problems. Our math site has a comprehensive list of probability distributions with examples and equations to help you understand and solve problems. We also provide step-by-step solutions with answers and explanations to help you learn and understand the concepts better. Check out our questions to get help with probability distributions.
