ted value of a random variable X, denoted by E[X], is defined by two separate Definition 3.3. One formula is for discrete random variables and involves a the other formula is for continuous random variable and involves an integral. mula for handling discrete random variables, continuous random variables, and mixed discrete-continuous random variables in terms of the cumulative distributio 6 The expect function of X, that is, F(x), is F(x)dx+(1-F(x) dx. Apply this formula to (a) a discrete random variable...
