Answer:
The total number of possible passwords is 720.

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,
