How many 3 digit codes are there?
There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6.
How many 6 digit codes are possible?

What is every possible combination of 0 9?
How many different 6 digit PIN codes using only the digits 0-9 are possible?
Berry analyzed passwords from previously released and exposed tables and security breaches, filtering the results to just those that were exactly four digits long [0-9]. There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code.
