Laposte France,Collisimo France,Chronopost France uses 13 digits! and these are tied up with different courriers in different countries-In turn they also use same 13 digits
There are infinitely many numbers in each system, however base 10 uses 10 digits {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} and binary uses 2 digits {0, 1}. The maximum digit is one less than the base.
If you allow the first digit to be zero, then you can form (5 x 4 x 3 x 2 x 1) = 120 numbers. If the first digit can't be zero, then you can only form (4 x 4 x 3 x 2 x 1) = 96 numbers.
Think of either using or not using the numbers 1 and 4 for each digit. For example, let ____ ____ _____ ____ be the 4 digit number, now 1 can either go in to the first spot or 4 can. So there are 2 choices for that spot, and similarly two for the next spot and the next and the last. So there are 2^4 =16 combinations of 1 and 4 if we make 4 digit numbers. (this uses the multiplication rule) To help a little more to see it, look at just the two digit number, It should have 2^2=4 choices by the logic above. Here they are: 11,14,41,44 and that's it!. See how we had two choices for each digit?
