Explanation / Answer

8) P(student gets a GED) = 0.09 * 0.2 = 0.018

b) P(listen music | female) = P(listen music and female)/P(female) = 18/(56 + 18 + 29 + 43) = 0.12

c) n = 7

p = 0.13

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

               = 1 - P(X = 0)

              = 1 - (7C0 * (0.13)^0 * (0.87)^7)

              = 1 - 0.0233

              = 0.9767
