15.2.65 One dimensional random variables and their characteristics
condition: The product is considered the highest grade if its weight does not exceed 10 g in absolute value. The weighing error is subject to the normal law with parameters \( (0.20) \). Find the average number of premium products if 3 products are manufactured. The parts are weighed independently.
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.
