Homework Help: Given a general probability, determining the probability in a set

  1. Mar 2, 2010 #1
    1. The problem statement, all variables and given/known data

    The probability of a silicon chip to be defect is .61 at the final production line.
    What is the probability that exactly 6 of the 14 chips are NOT defect?

    2. Relevant equations



    3. The attempt at a solution

    P(A)=.61
    P(A')=.39 (since we are going to be looking for the probability that we won't have a defective chip)

    Now the probability that 6 of those 14 won't be defective is ???

    If there is a 39% chance of success for the total 14 chips, how do I relate that to only 6 of them?


    Help me visualize this since I am utterly horrible at statistics

    <b>EDIT: Just found out this is a Binomial Distribution problem and found the answer by plugging and chugging the values into the formula</b>
