Theoretical Distributions: Some Special Discrete Distributions

Having developed the general pmf/cdf/mean/variance machinery, this section studies four named discrete distributions of special importance, in increasing order of richness: the one-point distribution (all mass at a single value), the two-point distribution (mass split between two values), the Bernoulli distribution (the two-point distribution specialised to a $\{0,1\}$-valued success/failure trial), and the binomial distribution …
