Consider independent and identically distributed random variables X 1 , X 2 , X 3 ,
Question:
Consider independent and identically distributed random variables X1, X2, X3, … where each Xi has a discrete uniform distribution on the integers 0, 1, 2, …, 9; that is, P(Xi = k) = 1/10 for k = 0, 1, 2, …, 9. Now form the sum
Intuitively, this is just the first n digits in the decimal expansion of a random number on the interval [0, 1]. Show that as n → ∞, Un converges in distribution to an rv U uniformly distributed on [0, 1], i.e. that P(Un ≤ u) → P(U ≤ u), by showing that the moment generating function of Un converges to the moment generating function of U.
