Answer: There are 1000 different passwords.
Step-by-step explanation:
Given: A password contains three digits.
Number of digits from 0 to 9 = 10
Using fundamental principle of counting,
The number of different passwords = (Number of choices for digits) x (Number of choices for digits) x (Number of choices for digits)
= (10) x (10)x (10)
=1000
Hence, there are 1000 different passwords.
