A password contains three digits, such as 175. How many different passwords can be formed?

Answer 1

Since the password contains three digits, and each digit can be chosen from the set of 0-9 digits, there are 10 choices for each digit.

Therefore, the total number of different passwords that can be formed is 10 choices for the first digit multiplied by 10 choices for the second digit multiplied by 10 choices for the third digit.

This can be calculated as: 10 * 10 * 10 = <<10*10*10=1000>>1000.

Therefore, there are 1000 different passwords that can be formed.
