If X denotes the number of heads obtained then X is a discrete random variable. Remarks The sample space S for discrete random variable can be discrete, continuous, or it may contain both discrete and continuous points.Discrete random variables are the random variables whose range is finite or...
A random variable is said to be discrete if the set of values it can take (its support) has either a finite or an infinite but countable number of elements. Its probability distribution can be characterized through a function called probability mass function. ...
Keywords:Random Variables,Discrete Distributions,Uniform Distributions on Integers,Binomial Distributions 开篇废话 目前阶段,每天研究数学,数学和技术的最基本差别是数学基本不能马上变现,而技术不一样,学个java或者php你可以在三到五个月内找到工作,三到五个月微积分计算都学不透彻,更别说用这个挣钱了,所以学数学基...
Continuous vs discrete In order to sharpen our understanding of continuous variables, let us highlight the main differences with respect to discrete variables found so far. The main characteristics of a discrete variable are: the set of values it can take (so-calledsupport) is countable; ...

Discrete Random Variables Say, for example, that an experiment involving flipping a coin is performed. The two different options for the outcome can be easily numbered, with one of them being heads and another one tails. It is also possible to associate each outcome with a probability: for a...

The probability of some random variable, X, taking on some discrete value, k, is given by: Here, λ is the mean number of events that you expect to occur in the timescale under consideration, e is Euler’s constant (2.72), and k is the number of events whose probability you wish to...
