,xk,…and if the set of those outcomes at which ξ takes the value xk is an event (ξ = xk) with a well-defined probability for each k. The probability pk is a function of xk. This function is called the probab
A random variable X is said to be continuous if its set of possible values is an entire interval of numbers -- that is, if for some A<B, any number x between A and B is possible. Probability Distribution of Continuous Variables Let X be a continuous rv. Then aprobability distributionor...
Hypergeometric Distribution The probability distribution of X is: x 1 2 Total f(x)= P(X=x) 1.00 Hypergeometric Distribution Definition 3.5: The cumulative distribution function (CDF), F(x), of a discrete random variable X with the probability function f(x) is given by: for <x<...

Probability Distribution A probability distribution is an assignment of probabilities to the specific values of a random variable, or to a range of values of the random variable. Discrete: probability assigned to each value of the random variable (and the sum = 1) ...
Distribution Function The distribution function (d.f.) or cumulative distribution function (c.d.f.) F of a random variable X is the function F(x)=Pr(X≤x) for −∞<x<∞ Importance: Always valid to describe the distribution of a RV Property ...

The pattern of probabilities for a random variable is called its probability distribution. Many random variables have a mean and a standard deviation. In addition, there is a probability for each event based on a random variable. We will consider two types of random variables: discrete and ...
This is also true for a continuous probability distribution: The area of the region under the curve is 1, and the areas of vertical slices of the region—similar to the bars of a histogram—are equal to probabilities of a random variable associated with the distribution. Such a random variab...
