    Answer:

    33124 passwords can be created using this format

    Step-by-step explanation:

    The password will have the following format:

    L – L – D – D

    There are 26 letters and 7 digits, so the number of possible outcomes in each position is:

    26 – 26 – 7 – 7

    How many passwords can be created using this format?

    26*26*7*7 = 33124

    33124 passwords can be created using this format
