Harry was busy arranging books on a book shelf at the Wide Horizons Book Shop<\/em>. Harry was positioning two copies of Inferno<\/em>,\u00a0 three copies of The Da<\/em> Vinci Code<\/em> and four of Origin<\/em>.<\/p>\n\n\n\n

A little boy stood there watching Harry.<\/p>\n\n\n\n

\u201cI\u2019ll bet you don\u2019t know in how many ways you can arrange those books on\nthe shelf,\u201d said Lenny teasingly.<\/p>\n\n\n\n

Harry looked behind him and saw the grinning, mischievous face of a five-year\nold looking up at him.<\/p>\n\n\n\n

\u201cWell, obviously in just six ways, kid,\u201d said Harry.<\/p>\n\n\n\n

\u201cNot if you mix all the books in all possible ways,\u201d replied Lenny impishly.<\/p>\n\n\n\n

\u201cWhat a pesky kid,\u201d said Harry backing off to stand away from the book\nshelf and scratch his head.<\/p>\n\n\n\n

\u201cJust to give you a hand, mister, check how many different words you can make with the letter group \u2018mississim\u2019 and you\u2019ll have the answer. That way you won’t have to move the books around,\u201d said Lenny on his way out of the store.<\/p>\n\n\n\n

In how many different ways would you say the books can be arranged?<\/em><\/p>\n
