In probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of possible outcomes for an experiment. [1] [2] It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space). [3]
9 cze 2022 · A probability distribution is a mathematical function that describes the probability of different possible values of a variable. Probability distributions are often depicted using graphs or probability tables. Example: Probability distribution. We can describe the probability distribution of one coin flip using a probability table:
23 kwi 2018 · A probability distribution is a statistical function that describes the likelihood of obtaining all possible values that a random variable can take. In other words, the values of the variable vary based on the underlying probability distribution.

A distribution function determines the probability mass in each semiinfinite interval \ ( (\infty, t]\). According to the discussion referred to above, this determines uniquely the induced distribution. The distribution function \ (F_X\) for a simple random variable is easily visualized.
The normal distribution is extremely important because: many real-world phenomena involve random quantities that are approximately normal (e.g., errors in scientific measurement); it plays a crucial role in the Central Limit Theorem, one of the fundamental results in statistics;
