## ABSTRACT

Figure 3.1 shows an example of the Bernoulli distribution. The mean, E[X], and the variance, Var[X], for the Bernoulli distribution

are given by

[ ]E X p= (3.2)

and

( )= −[ ] 1Var X p p (3.3) respectively. Ayyub and McCuen (1997, p. 91); Hoel, Port, and Stone (1971, pp. 66, 83); Mood, Graybill, and Boes (1974, p. 87).
