Среднее значение случайной величины | Теория вероятностей

We continue our lecture course on probability theory, which you can find in the Elements of Probability Theory playlist at    • Элементы теории вероятностей   Today's lecture topic is the mean value of random variables. This is a continuation of the lecture on random variables, which you can watch at    • Случайные величины | Теория вероятностей   Today we'll talk about the usefulness of the mean value of a random variable, which can only be determined from a probability distribution table. How can the mean value be useful? Let's try to find the answer in this lecture. Read by Igor Tinyakov #probabilitytheory #elementarymathematics #randomvariable #meanvalueofrandomvariable #meanvalue
