The F-distribution, also known as the Fisher-Snedecor distribution, is a continuous probability distribution that is often used in hypothesis testing and analysis of variance (ANOVA). It is typically used to compare the variability of two population samples or to determine whether two population variances are equal. The F-distribution is a right-skewed distribution with a minimum value

 The Student’s t-distribution is a continuous probability distribution that is used to estimate the mean of a normally distributed population when the sample size is small, and the population variance is unknown. It is often used in hypothesis testing and confidence interval estimation, particularly when the sample size is small and the population variance is

 The Poisson distribution is a probability distribution that describes the likelihood of a given number of events occurring in a fixed time period or in a fixed area. It is often used to model the number of times an event occurs in a given period, such as the number of customers arriving at a store

 The binomial distribution is a probability distribution that describes the likelihood of a given number of successes in a fixed number of trials. For example, in the case of flipping fair coins, the binomial distribution can be used to calculate the probability of getting a certain number of heads in a certain number of coin

Several probability distributions are used in statistics. These include the three most commonly used distributions: the Normal Distribution, the Binomial Distribution, and the Poisson Distribution.Three Most Commonly Used Distributions:1. Normal Distribution: The normal distribution is a continuous probability distribution that is symmetrical around the mean. It is often used to model normally distributed data, such
