15.2.64 One dimensional random variables and their characteristics
condition: The discrete random variable \( X \) can take only two values: \( X_{1} \) and \( X_{2} \), and \( X_{1}
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.
