    a. (.70)^5 = 0.16807

    b. (.70)^4 * (.70)^5 = 0.117649

    c. assuming that most = 3

    (.70)^3 = 0.343

    n=5
    p=0.7
    a)
    (0.7)^5 = 0.16807

    b)
    (0.7)^4 * (0.3) * C(5 ,4) + (0.7)^5 = 0.36015 + 0.16807 = 0.52822

    c)
    (0.7)^3 * (0.3)^2 * C(5,3) + (0.7)^4 * (0.3) * C(5, 4) + (0.7)^5 = 0.3087 + 0.36015 + 0.16807 = 0.83692


    EDIT:Before you're confused
    C(5,3) =P(3)
    C(5,4) =P(4)
