2.4 The Binomial Distribution
A. Bernoulli Distribution
A r.v. X is called a Bernoulli r.v. with parameter p if its p.m.f. is given by
f (x) = P (X = x) = px (1 p)1x
x = 0, 1
where 0 p 1.
A Bernoulli r.v. X is associated with some e

Bernoulli Distribution
A random variable X has a Bernoulli distribution if
Pr(X = 1) = p and Pr(X = 0) = 1 p = q
The p.m.f. of X can be written as
p x q1 x for x 0, 1
