A random variable is a variable whose value depends on the outcome of a probabilistic experiment. Its value is a priori unknown, but it becomes known once the outcome of the experiment is realized. Definition Denote by the set of all possible outcomes of a probabilistic experiment, called asam...
Almost sure convergence(also calledconvergence in probability one) answers the question:given a random variable X, do the outcomes of the sequence Xnconverge to the outcomes of X with a probability of 1?[4]. As an example of this type of convergence of random variables, let’s say an ento...
In practical use, the meaning of random variable can be intuitively understood to be a variable that may take on different values randomly but whose value is not known. More specifically, random variable definition is as a set of possible outcomes, called a sample space, along with a ...
See Statistics - Continuous Variable ie taking any numerical value in an interval or collection of intervals, via a probability density function that is characteristic of the random variable's probability distribution; or a mixture of both types. Spinner that can choose a horizontal direction The ...
In statistics, independent variables describe events with outcomes that are independent of each other. An example could be that of two successive coin tosses. What is an example of an independent random variable? An example of independent random variables would be the height of a student and thei...
Another consequence of the definition given above is that the support of a continuous random variable must be uncountable. In fact, by the previous property, if the support (the set of values the variable can take) was countable, then we would have ...

A random variable is different from an algebraic variable. The variable in an algebraic equation is an unknown value that can be calculated. The equation 10 + x = 13 shows that we can calculate the specific value for x which is 3. A random variable has a set of values and any of thos...
