Three balls are to be randomly selected without replacement from an urn containing 20 balls numbered 1 through 20. The random variable X is the largest number in the selection. Write down the probability mass function of X. If we bet that at least one of the drawn balls has a number as large as or larger than 17, what is the probability that we will win?
