RANDOM VARIABLES AND PROBABILITY DISTRIBUTIONS
www2.econ.iastate.eduProbability distribution for a discrete random variable. The probability distribution for a discrete random variable X can be represented by a formula, a table, or a graph, which provides p(x) = P(X=x) for all x. The probability distribution for a discrete random variable assignsnonzero probabilities toonly a countable number ofdistinct x values.

Applications of the Poisson probability distribution
www.aabri.comThe Poisson distribution is a probability distribution of a discrete random variable that stands for the number (count) of statistically independent events, occurring within a unit of time or space (Wikipedia-Poisson, 2012), (Doane, Seward, 2010, p.232), (Sharpie, De Veaux,
