15.2.69 One dimensional random variables and their characteristics
condition: A continuous random variable has a distribution density \[ f(x)=\left\{\begin{array}{l} 0, \quad-\infty
Study of discrete and continuous one-dimensional random variables, calculation of their characteristics such as mathematical expectation, variance, standard deviation, moments, distribution and density functions. We also consider problems on known distributions - Gauss, Bernoulli, Poisson. Finding the probabilities of various events, including those from everyday life.
