WebTheorem Just as we did for a geometric random variable, on this page, we present and verify four properties of a negative binomial random variable. The probability mass function: f ( x) = P ( X = x) = ( x − 1 r − 1) ( 1 − p) x − r p r for a negative binomial random variable X is a valid p.m.f. Proof Web14.6 - Uniform Distributions. Uniform Distribution. A continuous random variable X has a uniform distribution, denoted U ( a, b), if its probability density function is: f ( x) = 1 b − a. for two constants a and b, such that a < x < b. A graph of the p.d.f. looks like this: f (x) 1 b-a X a b. Note that the length of the base of the rectangle ...
