If 10% of all disk drives produced on an assembly line are defective, what is the probability that there will be exactly one defect in a random sample of 5 of these? What is the probability that there will be no defects in a random sample of 5?

    solution:

    p=ncx,. p^x. Q^{n-x}//

    where p and q are the probabilities of success and failure respectively.//

    in this case p = 0.10 and Q=0.90//

    ncx = / frac{n!}{x! (n-x!) }//

    p (exactly one defect in a random sample of 5) / /

    =5 (0.10) ^1 (0.90) ^4=0.3281//

    p (no. defects in a random sample of 5) / /

    =1 (0.90) ^5=0.5905
