Answer:
Explanation:
To calculate the number of different passwords that are possible, we need to consider the number of choices for each component of the password.
For the letter component, there are 26 choices (assuming we are considering only lowercase letters).
For the first digit, there are 10 choices (0-9), and for the second and third digits, there are also 10 choices each.
Since the components of the password are independent of each other, we can multiply the number of choices for each component to determine the total number of possible passwords:
Number of passwords = Number of choices for letter * Number of choices for first digit * Number of choices for second digit * Number of choices for third digit
Number of passwords = 26 * 10 * 10 * 10 = 26,000
Therefore, there are 26,000 different possible passwords that consist of 1 letter and 3 digits.
