About

Bernoulli Process PRO

Features
Read full description

A Bernoulli process or Bernoulli chain is a series of stochastically independent Bernoulli experiments. This app calculates the result of a Bernoulli process. Therefore it needs the probability, hits and trials. And it shows the histogram of the Bernoulli process, distribution function chart and probability tree (tree chart). Depending on variable, natural numbers or decimal numbers are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - Bernoulli process with the Bernoulli function - probability p, hits k and trials n must be entered - results are calculated and shown in detail - histogram, distribution function chart and probability tree - history to save the input - detailed solution - natural or decimal numbers are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, the corresponding field is highlighted in yellow - if the values are incorrect, the affected field will be highlighted in red - a short message explains why a value is incorrect - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared - p must be greater than 0 and less than 1 - k must be greater than or equal to n
