There are 720 different possible codes
The total number of single digits is 10 i.e. 0 to 9
The identification code is 3 digits
Given that each digit cannot be repeated, then we have the following scenarios
- Any of the 10 digits can represent the first digit
- Any of the remaining 9 digits can represent the second digit
- Any of the remaining 8 digits can represent the third digit
So, the number of possible code is:
[tex]Code = 10 * 9 * 8[/tex]
[tex]Code = 720[/tex]
Hence, there are 720 different possible codes
