Теория вероятностей #9: Дискретные случайные величины / функция вероятности и распределения

In this video, we'll define random variables and take a detailed look at discrete random variables. We'll learn how to define their distribution using a probability function and a distribution function. We'll pay special attention to the distribution function: we'll examine its properties and explore how it can be used to calculate interval probabilities of a random variable. 0:00 Start 2:52 Random Variables: Definition 6:28 Distribution of a Random Variable 8:20 Discrete and Continuous Random Variables 11:00 Probability Function 14:37 Distribution Function 22:55 Properties of the Distribution Function 25:49 Sigmoid as an Example of a Distribution Function 29:12 Calculating Interval Probabilities Subscribe to our Telegram channel for additional materials, information about new courses, news from the world of mathematics and data science, and much more: https://t.me/getsomemath Contacts: http://apershin.com
