I am assuming the following: a) The books are picked one at a time. b) there is no replacement. i.e. Total number of books = b a) Number of ways of choosing the first book out of b books is b because I can choose either the book in slot 1, or slot 2 ... up to the book in slot b Remaining books = b-1. b) Number of ways of choosing the second book = b-1 Because there are only b-1 slots holding b-1 books Remaining books = b-2 c) Number of ways of choosing the third book is b-2 But the total number of ways of choosing the first 3 books is b*(b-1)*(b-2)
