Notes on random variables
... Example 2. Consider a stock price which moves each day either up one unit or down one unit, and suppose its initial value is 10$. Let T be the first time the value of the stock hits either 0$ or 20$. Then T is a random variable. Example 3. The lifetime T of a lightbulb is a random variable. In the l ...
