Question 806320: How many different ways can 12 books be arranged on a shelf? How about 52 playing cards? If the above are rearranged once every second, bow long will all the permutations take to complete?

You can put this solution on YOUR website!
12! for the books,
52! for the cards
It would take over 15 years to rearrange the books that many times, IF you never stopped to sleep, eat, use the bathroom, or anything else.
As for the cards, if you had started at the instant of the Big Bang, you would not have even made a dent in the  permutations. You would only have managed to create  of them, or about  percent of the whole job.
