A certain country's postal service currently uses 5-digit zip codes in most areas. How many zip codes are possible if there are no restrictions on the digits used? How many would be possible if the first number could not be 0?
A. To use an automated teller machine at a certain bank, you must enter a 4-digit code, using the digits 1–9. How many 4-digit codes are possible if repetition of digits is permitted? B.

Suppose that a "code" consists of 5 digits, none of which is repeated. (A digit is one of the 10 numbers 0,1 2,3 4,5 6,7 8,9.) How many codes are possible?
Given the digits 5, 4, 2, 0, 3, 7, 9, 6, 8. How many three-digit number codes can be formed if the hundreds place must be even and the ones place is at least 5? No repition
How many different 3 digit numbers less than 500 can be made using the digits 3, 4, 5, and 6 if the digits can be used only once
Consider the number 35964 How many 3 digit numbers can be formed using digits from 35964 if no digits may be repeated? What is the sum on all of those 3 digit numbers?
How many 4-digit numbers can be formed using only the digits {1,2,3} if repetition is allowed and the number must contain the digit 3 somewhere. Hint: it may be easier to first count the numbers that don't contain the digit 3.
