Lecture 5 introduces the concept of a random variable. We discuss the concepts of discrete random variable, probability distribution, probability mass function and cumulative distribution function. In the second part we describe several important distributions of discrete random variables Timeline: 00:00 Independent events 19:49 A concept of a random variable 27:37 Discrete random variable 29:29 Probability distribution 32:52 Probability mass function 35:59 Cumulative distribution function 50:20 Bernoulli distribution 57:42 Binomial distribution 1:11:09 Geometric distribution The course “Probability“ for the 2nd year bachelors in Economics Taught at BRICS institute, Irkutsk National Research Technical University, Winter semester 2021
