"WebbRandom variables The idea above of converting an outcome described in words (e.g. BBG) into a numeric summary of the outcome (e.g. 2 boys) is the de nition of a random variable. Instead of writing P (2 boys) above, we give the unknown numerical outcome a capital letter, say X . X is called a variable because it is a variable number, and it is ...

WebbIn Lesson 2, we introduced events and probability properties. In this Lesson, we will learn how to numerically quantify the outcomes into a random variable. Then we will use the random variable to create mathematical functions to find … WebbThe probability assigned to each value of the random variable x is denoted by Px(xi). Here the subscript x refers to the random variable whereas the argument xiis the particular value of the random variable. Thus Px(xi) is the probability that a …

WebbA random variable X has a Bernoulli distribution with parameter p, where 0 ≤ p ≤ 1, if it has only two possible values, typically denoted 0 and 1. The probability mass function (pmf) of X is given by p ( 0) = P ( X = 0) = 1 − p, p ( 1) = P ( X = 1) = p. The cumulative distribution function (cdf) of X is given by WebbNote that, if is a continuous random variable, the probability that takes on any specific value is equal to zero: Thus, the event is a zero-probability event for any . The lecture on Zero-probability events contains a thorough discussion of this apparently paradoxical fact: although it can happen that , the event has zero probability of happening.
