**PACK OF CARDS**** - SHUFFLE THE PACK. HOW MANY
PERMUTATIONS ARE THERE? Or, to put it another way, if you
shuffled two packs of cards separately, what would be the chance
(in terms of "n:1") they'd be in the same order?**

**Answer is:**

**80658175170943878571660636856403766975289505440883277824000000000000**

**Or about 8 x 10**^{67}**
. To work this out it's 52 x 51 x 50 x 49 x 48 ... x 3 x 2 x 1.
How would you work this out, apart from by spending too long
using a calculator? This is where it gets interesting.**

**Using a COMPUTER is the
answer. But not the sort of thing you see calling itself a
computer these days (2001/03). The idea that a computer is
actually PROGRAMMABLE is the thing. Any computer is in theory
programmable, it's just that it's gone out of fashion. Or has it...
see ****computer programming****. Computer programming is a good
idea, recommended!**

**Or maybe you're into the
gambling side of things. If so, you might like to look at the ****Gambling
