If all numbers have a 1/10 chance of selection, why is a combination like “3478” safer than “0000” or “1234” for a PIN?

It depends on how the password is being tested. If it’s just a random number generator trying random numbers, then 1234 is just as safe as 9483. But if the hacker tries some “common sense” passwords to begin with, then he is likely to try 1234 and unlikely to try 9483. To avoid this we consider 1234 to be unsafe.
