What is the Bernoulli test? Its relationship with binomial distribution.
Definition of Bernoulli test. The test with only two results A and -A is called Bernoulli test.

If N Bernoulli tests are independently conducted under the same conditions (that is, the results of each test do not affect each other), and the probability of event A in each test remains unchanged, the test is called N-fold Bernoulli test.

N-fold Bernoulli test is a very important probability model, and many practical problems can be summed up in this model, which is usually called Bernoulli probability model. The important difference between it and the classical probability model is that its sample points are not necessarily equal probability, and it is often used to discuss the number and probability of event A in n repeated experiments.

When the number of times is n, it is similar to binomial distribution.
