Abstract
The main properties of discrete probability distributions are presented. Joint, marginal, and conditional distributions are introduced, with the main statistical indicators: average, variance, etc. The problem of determining the probability distribution under variable transformation is presented. The most frequently used discrete distribution are introduced: Bernoulli, binomial, multinomial and Poisson, and their properties are discussed. The law of large numbers is introduced, and its importance under the frequentist approach to probability is discussed.

The coefficients present in the binomial distribution are the same that appear in the expansion a binomial raised to the nth power, (a + b)n. A simple iterative way to compute those coefficients is known as Pascal’s triangle . In different countries this triangle is named after different authors, e.g., the Tartaglia’s triangle in Italy, Yang Hui’s triangle in China, and so on. In particular, the following publications of the triangle are present in literature: • India: published in the tenth century, referring to the work of Pingala, dating back to fifth–second century bc. • Persia: Al-Karaju (953–1029) and Omar Jayyám (1048–1131) • China: Yang Hui (1238–1298), see Fig. 2.3 • Germany: Petrus Apianus (1495–1552) • Italy: Nicolò Fontana Tartaglia (1545) • France: Blaise Pascal (1655)
