0, unless you write the first 9 as 01, 02, 03 etc. All the rest tie except 1, which is most frequent, only because 100 is included. In a list from 1-99, digits 1-9 all tie. You're welcome, from an overthinker.

You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
3 digit numbers are lessthan 4 digit numbers

The 3 digit numbers under 500 are 100 through 499.
You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.

There are 90 two digit numbers, 10 through 99. There are 18 two digit numbers containing a 9. They are 19, 29, 39, 49, 59, 69, 79, 89, and 90 through 99. Therefore, there are 72 two digit numbers that do not contain a 9.
All whole, three-digit numbers from 450 through 549 (when rounding to the nearest hundreds).
It is a system based on the place value.
3 digit numbers are lessthan 4 digit numbers
Without restrictions, it was would numbers 000-000-0000 through 999-999-9999. So that would be 9,999,999,999 + 1 = 10 billion different 10-digit phone numbers. Ex: If there existed single digit phone numbers, there would be 10, because the digits are 0 through 9. If there existed only double digit phone numbers, then it would be 00 through 99 which would be 100 total two-digit numbers. Therefore the total possible combinations for an X digit phone number would be: 10^X
