    Work Question - Non Mathematician

    I have been asked a question at work and don't know where to start. Please help

    If you have four questions to be answered together. Each answer can have twenty possible answers and all the answers can have two sub conditions, how many different combination of answers can you get.

    Thanks

    20 \times 2 = 40 possible answers for each question (with sub-conditions).

    The first answer can be chosen in 40 ways.

    The second answer can be chosen in 40 ways.

    The third answer can be chosen in 40 ways.

    The fourth answer can be chosen in 40 ways.

    So, total number of different combinations = 40^4 = 2560000.

    I hope that helps.
