Limit of a random variable
A significant theme in mathematical statistics consists of obtaining convergence results for certain sequences of random variables; for instance the law of large numbers and the central limit theorem. There are various senses in which a sequence of random variables can converge to a random variable . These are explained in the article on convergence of random variables. NettetA random variable is a rule that assigns a numerical value to each outcome in a sample space, or it can be defined as a variable whose value is unknown or a function that gives numerical values to each of an experiment’s outcomes. What is …

NettetThe Central Limit Theorem. The central limit theorem (CLT) asserts that if random variable \(X\) is the sum of a large class of independent random variables, each with reasonable distributions, then \(X\) is approximately normally distributed. This celebrated theorem has been the object of extensive theoretical research directed toward the … Nettet$\begingroup$ If you have several random variables, then practically any combination of them will be a random variable. :) $\endgroup$ – Caran-d'Ache Mar 30, 2013 at 14:55

In the case of this example an outcome is an element in the sample space (not a combination) and an event is a subset of the sample space. An event occurs if any of its elements occur. A random variable is a function from the sample space to the reals. The concept of event is more basic than the concept of random variable.

The Law of Large Numbers predicts that the outcomes for this random variable will, for large n, be near 1/2. In Figure [fig 8.1], we have plotted the distribution for this example for increasing values of n.
