Explanation / Answer

1) p = 0.71

n = 5

P(X > 1) = 1 - P(X < 1)

             = 1 - P(X = 0)

             = 1 - (5C0 * (0.71)^0 * (0.29)^5)

            = 1 - 0.002

            = 0.998

b) P(A or B) = P(A) + P(B) - P(A and B)

                    = 0.14 + 0.81 - 0.05

                    = 0.9

P(not A and not B) = 1 - P(A or B)

                              = 1 - 0.9 = 0.1

P(not B | not A) = P(not B and not A)/P(not A)

                             = 0.1/(1 - 0.14)

                             = 0.1/0.86 = 0.116
