1.) An office supply store has 6 coffee pots of the same make and model 3 of which are broken. An office clerk selects three of these coffee pots for their employer at random. Let y be the random variable (RV) denoting the number of good coffee pots in the group of 3 for use by the employer. Respond to the following: a.) What is the probability mass function (pmf) of the RV Y? b.) Use your pmf from the question above to graph the cumulative distribution function (CDF) of the RV Y.
