b) Probability of exactly two = 0.06 ii) Probability of more than two = P(3) + P(4) +P(5) +P(6) = 0.28 + 0.12 +0.0 + 0.94 = 0.78 iii) Probability of atleast three = P(3) + P(4) +P(5) +P(6) = 0.28 + 0.12 +0.0 + 0.38 = 0.78 f) Probability of success = Probability of person being involved in sales or occupation “2” = 0.06 Hence, probability of failure =
