Answer 1

19,958,400

Explanation:

There are 12 ways the photographer could go in picking the first card.

After picking the first one, there will be 11 ways left for the second.

After picking the first one, there will be 10 ways left for the third, and so on...

So our answer = (12)(11)(10)(9)(8)(7)(6)(5) = 19,958,400
