A distribution associates a probability (a number lying between 0 and 1) with each possible outcome; the sum of these probabilities must be unity. In distribution theory the probabilities are values of a mathem
Proof: For finite sample spaces, these are characteristics of the probability functionP(E)per Property 1 ofBasic Probability Concepts. They also hold for infinite discrete sample spaces, but we need not get into the details here. Observation: Iffis the frequency function of a discrete randomxwith...
TheBinomial distributionis the discrete probability distribution of the number of successes in a sequence ofnindependent Bernoulli trials with success probabilityp, denoted asX~B(n, p). The Binomial distribution is often used to model the number of successes in a sample of sizendrawn with replaceme...

Discrete probability distribution The probability distribution of any random variable is discrete in nature, if the range of the random variable is defined at discrete points only. The range can be finite or countably infinite. The probability mass function defined gives the value of the probability...
II. Discrete Probability Distributions Describes how probabilities are distributed over the values of the random variable. A. Probability function For a discrete r.v. x, the probability distribution is defined by f(x), the d.p.f. f(x)0 ...

This paper provides specific directions for the preparation of a discrete pseudo-random number generator computer program using basic machine instructions. The scheme is a table look-up first suggested by Marsaglia. It is applicable to any discrete probability distribution. The general procedure is ...

The dependence structures of the bivariate distributions belonging to the proposed classes, along with basic statistical properties, are also discussed. New families of discrete bivariate distributions are generated from the classes. Furthermore, to assess the usefulness of the proposed classes, two ...
