At the beginning of a semester, a college bookstore has 26 used statistics textbooks and 74 new statistics textbooks in stock on the shelf. a) If a bookstore clerk chooses a statistics textbook at random from the shelf, what is the probability that it will be a used book?

b) If a stat book is selected as random, what is the probability that it will be a used book or a new book?

c) If the clerk grabbed two stat books, what is the probability that both would be used books?

d) If the clerk were to choose 5 statistics books from this shelf, could we use binomial probabilities to determine the probability that exactly 2 of them were used books? Explain.
