An urn contains 9 $1 bills and one $50 bill. Let the random variable X be the total amount that results when two bills are drawn from the urn without replacement. a). Describe the underlying space S of this random experiment and specify the probability of its elementary events.
b). Show the mapping from S to Sx, the range of X.
c). Find the probabilities for the various values of X.
