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 D
which is 3. A random variable has a set of values, and any of those values could be the resulting outcome, as seen in the example of the dice.2

A random variable is a measurable function from a probability space (S,S,P) into a measurable space (S^',S^') known as the state space (Doob 1996). Papoulis (1984, p. 88) gives the slightly different definition of a random variable X as a real function w

3.3.2 How to check a random variable? 如何检验随机变量呢?其实就是在检验可测函数。定理3.3.1告诉我们检验的方法。不需要使用随机变量的原始定义:检验对所有的Borel集B都有X^{-1}(B),满足X^{-1}(B)\in\mathcal{A}。只需要检验X^{-1}([-\infty,x])\in\mathcal{A} ,\forall x\in\mathcal{...
Definition A random variable is some function that assigns a real number X(s) to each possible outcome s∈S, where S is the sample space for an experiment. Random Variable (R.V./r.v.) is essentially a function (mapping) from sample space Ω to real number set R, i.e., mapping a...
