Random variable assigns probabilities to intervals; in particular, each individual point must necessarily have probability zero for an absolutely continuous random variable. Not all continuous random variables are absolutely continuous, for example a mixture distribution. Such random variables cannot be described by a probability density or a probability mass function. Any random variable can be described by its cumulative distribution function, which describes the probability that the random variable will be less than or equal to a certain value. The term "random variable" in statistics is traditionally limited to the real-valued case (formula_6). In this case, the structure of the real numbers
