H ADM 201 Prelim I Spring 2007 Question 1A. 30 points (5 points each part). On a specific cruise, 89% of passengers use the pool, 58% use the casino, and only 3% of passengers use neither of these facilities. A) What is the probability a passenger uses at least one of these two facilities? Let P = {Passenger uses the pool}, C = {Passenger uses the casino}; C P = {Passenger uses neither pool nor casino}. P(P) = 0.89; P(C) = 0.58; P ( C P ) = 0.03 A = P(P C) A = 1 – P( C P ) = 1 – 0.03 A = 0.97 B) What is the probability a passenger uses both of these facilities? B = P(P C) B = P(P) + P(C) - P(P C) = 0.89 + 0.58 - 0.97 B = 0.5 C) If a passenger uses the casino, what is the probability they will also use the pool? C = P(P|C) C = P(P C)/P(C) = 0.5/0.58 C = 0.86 Question 1. Continued on next page. 2

H ADM 201 Prelim I Spring 2007 Question 1. Continued from previous page. D) If a passenger does not use the pool, what is the probability they do not use the casino? D = P(C’|P’) D = P( C P )/P(P’) = 0.03/(1-0.89) D = 0.27 E) Show that using the pool and using the casino are NOT independent events in EACH of the two ways stated below. In EACH case, after doing the math, state in one complete sentence why the mathematics you used illustrates why these events are not independent. i) Using the multiplication rule for independent events.
