You can put this solution on YOUR website! Consider numbers of length 5 over the ten digits 0 to 9. Suppose repetition is allowed. The numbers may begin with 0.
a) How many of these numbers have no 0?:: 9^5
-----------------------------------------------------------
b) How many of there numbers have at least one 0?:: 10^5-9^5
-----------------------------------------------------------
c) How many of these numbers have exactly three 0s?:: 9^2
