Exercise 3.1.3 (a) Given that the Lehmer random number generator used in the library
rng has a modulus of 231 − 1, what are the largest and smallest possible numerical values
(as a function of µ) that the function Exponential(µ) can return? (b) Comment on this
relative to the theoretical expectation that an Exponential(µ) random variate can have an
arbitrarily large value and a value arbitrarily close to zero.
