【数学】常见概率分布

Binomial Distribution: The binomial distribution describes the probability of obtaining a certain number of successes in a fixed number of independent Bernoulli trials. The binomial distribution has two parameters, the number of trials n and the probability of success p, 

Bernoulli Distribution: The Bernoulli distribution is a simple, discrete probability distribution that describes the probability of a single binary event (i.e., an event with only two possible outcomes, such as success or failure). The Bernoulli distribution has a single parameter, the probability of success p.

Poisson distribution: In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event

Gamma distribution: In probability theory and statistics, the gamma distribution is a two-parameter family of continuous probability distributions.
