Suppose that all the students registered to the probability and statistics course have to buy textbook. The 42 % of all students demand a new book, on the other hand the other 58% want a used text book. Consider randomly selecting 40 purchasers. The bookstore has 30 new and 30 used textbooks in stock. If 40 people come in one by one to purchase this text, what is the probability that all 40 will get the type of book they want from current stock? [Hint: Let X = the number who want a new copy. For what values of X will all 40 get what they want?]
