Stochastic processes are everywhere: Brownian motion, stock market fluctuations, various queuing systems all represent stochastic phenomena. If X(t) is a stochastic process, then for fixed t, X(t) represents a random variable. Yes - he mean taking one die, rolling it seven times and summing up each result into a total. (You could achieve the same result by rolling 7 dice all at once.) For example you roll a 5, then a 3, then a 2, then another 5, a 1, a 2 and a 4.

Everyday, you look in your box of cereal and if there are enough to fill your bowl for the current day, but not the next, and you are feeling up to it, you go and buy another box of cereal.
Examples of Stochastic Optimization Problems In this chapter, we will give examples of three types of stochastic op-timization problems, that is, optimal stopping, total expected (discounted) cost problem, and long-run average cost problem. The setup and solution of these problem will require the familiarity with probability theory. For 2020-07-24 A stochastic variable can, nevertheless, be incorporated in these models, to evaluate different possible scenarios.
