Sarah works in the library, shelving books. This can be boring at times, so naturally, she starts recording the genres of each
book as she puts them away, looking for if they are biographies (as those are her favourite). She notices that of the
hundreds of books she shelves per day, approximately 4% are biographies. Assume the genre of the books Sarah is
shelving is independent. What is the probability that the fifteenth book she shelves is the first biography she encounters
that day? (Geometric model)
