15.2.68 One dimensional random variables and their characteristics
Condition: The die is thrown 2 times. \( X- \) the number of triplets, \( Y- \) the smallest of the ones drawn. Fill out the table and find from it \( P(2 X>Y), M X, M Y \)
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.
