That is a blatant case of the statistician drowning in a lake with an
average depth of three feet.  You have to understand what the numbers
mean in real life.

It may take that long to visit all possible solutions, but they only
need one solution.  They may find a working solution after 35 seconds.
Just because they don't have time to try every solution doesn't mean
they won't fire up the machines for as long as they have in hopes of
cracking it in time.
