    In this experiment, both a fair four-sided die and a fair six-sided die are rolled (these dice both have the numbers most people would expect on them). Let Z be a random variable that represents the absolute value of their difference. For instance, if a 4 and a 1 are rolled, the corresponding value of Z is 3. (a) What is the pmf of Z? (b) Draw a graph of the cdf of Z

    The Emergency Room in a rural hospital is staffed in four six-hour shifts (labeled W, X, Y, Z). During any shift, an Emergency Room patient is attended to by either a general physician (G), a surgeon (R), or an intern (I).
