Answer:

The total number of possible passwords is 720.

Step-by-step explanation:

Jimmy has 10 digits (0-9) to make the password and repetition is not allowed.

So, we have to digits in three places.

For the first place, we can use all the 10 digits (0-9).

For the second place, we can only use 9 digits as the repetition is not allowed and we have already used one digit in first place.

Similarly, for the third place, we can only use 8 digits.

Now, using the fundamental principle of counting, the total number of possible ways to create the password will be,

[tex]n=10\times9\times8\\n=720[/tex]

Therefore, the total number of possible passwords is 720.
