If half the batch of 6,000 vials are contaminated, what is the probability of finding no contaminated vials if only two vials are selected from the total amount produced?

  • math - ,

    Use the binomial distribution.

    If you calculate by hand, here is a formula:

    P(x) = (nCx)(p^x)[q^(n-x)]

    x = 0
    n = 2
    p = .5
    q = 1 - p = .5

    Substitute into the formula and calculate.

    I hope this will help.
