Chris tries to throw a ball of paper in the wastebasket behind his back (without looking). He estimates that his chance of success each time, regardless of the outcome of the other attempts, is 1/3. Let X be the number of attempts required. If he is not successful within tin first 5 attempts, then he quits, and he lets X = 6 in such a case.
a. Draw the mass of X.
b. Draw the CDF of X.
