b From the Minitab Probability Density Function, read . c Use the Minitab Cumulative Distribution Function to find . 5.32 Define x to be the number of Americans who look for services close to the highway. Then,and . a and . b Since x can take only integer values from 0 to 25, this interval consists of the values of x in the range

The gamma function, (z) is used in various integrals, including probability distribution integrals; it is defined by the following equation. [A-25] We can derive a general recurrence relationship for gamma function values whose argument increases by one using integration by parts with u = tz-1 and dv = e-tdt.

Probability Density Function of X. In other words, the probability that X is in the set B can be found by integrating f over the set B. Since X must always take a value in the reals (ie. X(-∞,∞)), the following logically follows: P[X(-∞,∞)] = = 1. Also, any probability statement about X can be written in terms of f.
