Permutation/combination problem with 'coins'

454 Views Asked by At

I'm trying to solve a 'number of possible outcomes' problem. Here it be:

There are 7 unique and completely different ‘coins’ – each has 2 sides that are again each unique and completely different from all of the others. In essence there are 14 unique things assigned to 7 discreet objects. The coins would be randomly assigned a separate position – there are 7 unique positions. How many possible ways could those 7 unique coins (each with 2 sides) be combined?

For the sake of explanation, imagine the 'coins' are broken out like this:

Coin 1 (A/a); Coin 2 (B/b); Coin 3 (C/c); Coin 4 (D/d); Coin 5 (E/e); Coin 6 (F/f); Coin 7 (G/g)

And you would take those 7 coins and randomly select and flip 1, then the next, then the next, until all 7 coins are in all seven positions. How many possible outcomes are there? Thanks in advance!
