12% of voters in a recent election voted on the greens candidate,
if 10 people were randomly selected
what is the probability that exactly 4 people voted for the green candidate.

  • Statistics -

    Try the binomial probability formula:

    P(x) = nCx * p^x * q^(n-x)

    Note: * means to multiply; ^ means raised to the power of.

    x = 4
    n = 10
    p = .12
    q = 1 - p

    I'll let you substitute the values and take it from here.
