Ms Jones has 10 books that she is going to put on her bookshelf. Of these, 4 are mathematics books, 3 are chemistry books, 2 are history books and 1 is a language book. Jones wants to arrnage her books so that all the books dealing with the same subject are together on the shelf. How many different arrangements are possible?
Solution:There are 4! 3! 2! 1! arrangements such that the mathematics books are first in line, then the chemistry books, then the history books, then the language book. Similarly, for each possible ordering of the subjects, there are 4! 3! 2! 1! possible orderings of the subjects, the desired answer is 4! 4! 3! 2! 1! = 6912
Mathematicians! who! work! with! probability! are! highly! excitable! people!
