WebA discrete random variable is one which may take on only a countable number of distinct values such as 0,1,2,3,4,..... Discrete random variables are usually (but not necessarily) counts. If a random variable can take … WebNote 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.
WebThe probability that a continuous random variable X is exactly equal to a number is zero . Means and Variances of Random Variables: The mean of a discrete random variable, X, is its weighted average. Each value of X is weighted by its probability. To find the mean of X, multiply each value of X by its probability, then add all the products. The ... WebSince X and Yare both standard normal random variables, their mean is 0 and its. standard deviation is 1. So, X⇒N (0,12) Y⇒N(0,12) Explanation: X and Y are independent, so the occurence of X does not affect the occurence of X. By knowing that X and Yare independent, then.
WebIf the probability of a random variable taking any particular value is $0$, then the sample space must be infinite, and the probability of a repeated value (in a sequence of i.i.d. … WebIf the random variable X can assume an infinite and uncountable set of values, it is said to be a continuous random variable. When X takes any value in a given interval (a, b), it is …
WebI hope this explains the concept of random variable. There can be 2 types of Random variable Discrete and Continuous. Discrete which cannot have decimal value e.g. no. of people, we cannot have 2.5 or 3.5 persons and Continuous can have decimal values e.g. height of person, time, etc.. ... If the absolute value of x minus four equals zero, then ...
