    Question probability of defects in computers

    Hi!
    I am not very good at probability. Maybe because I was not able to attend some lessons.

    The topics that was covered in those lessons was The full probability and Bayes formula and independent repeated attempts.

    Quality control department of a computer firm received 16 computers. In every of them the probability to find a defect is 0,08.
    What is the probability, that

    a)the defect was found in all computers
    b)the defect was found in exactly 3 computers
    c)the defect was found in at least 2 computers

    Thanks for help.

    Why don't you at least show some effort.
    All you do is post a list of questions.
    And you tell that you don't or cannot attend lecture sessions?
    WHY? Are we expected to offer you a tutorial?

    Hi!

    I was not able to attend lectures, because I had my own issues I am not going to discuss here.

    I have lecture materials and I wil try to solve those questions.

    I just put the questions here to receive answers more quickly so when I have problems I can take a look at answrs here, because I have to do this homework till tomorrow evening.
