In all of William Shakespeare’s works, he used 884,647 different words. Of these, 14,376 appeared only once and 4343 appeared twice. If one word is randomly selected from a list of these 884,647 different words:

(a) What is the probability that the selected word appears only once?

(b) What is the probability that the selected word appears exactly twice?

(c) What is the probability that the selected word appears more than twice?

(d) Suppose that, instead of randomly selecting a word from the list of different words, you randomly select a word from a book of Shakespeare’s complete works by selecting a page, line, and word number from a random-digit table. Is the probability of selecting a word that appears exactly once larger, smaller, or the same as your answer to part (a)?
