How many 3 digits no are there such that each digit is distinct to each other?
For the first digit, you have 9 options (1-9; the 3-digit number would not start with 0). For the second digit, you also have nine options (any digit from 0-9, except the digit used for the first digit). For this third digit, you have only eight options, since two digits are "forbidden", regardless of what digits you used first. That gives a total of 9 x 9 x 8 combinations.

How many two-digits numbers are there in which the tens digit is greater than the ones digit?
If the first digit is 9, you have 9 options (0-8) for the second digit. If the first digit is 8, you have 8 options (0-7) for the second digit. Etc. This leaves you with the arithmetic series: 0 + 1 + 2 + 3 + ... + 9.
