"WebA.2 Conditional expectation as a Random Variable Conditional expectations such as E[XjY = 2] or E[XjY = 5] are numbers. If we consider E[XjY = y], it is a number that depends on y. So it is a function of y. In this section we will study a new object E[XjY] that is a random variable. We start with an example. Example: Roll a die until we get a 6.
