1. At many airports, a traveler entering the U.S. is sent randomly to one of several stations where his passport and visa are checked. If each of the 6 stations is equally likely, can the probabilities of which station a traveler will be sent be modeled with a Uniform model?

2. At the airport entry sites, a computer is used to randomly decide whether a traveler's baggage should be opened for inspection. If the chance of being selected is 12%, can you model your chance of having your baggage opened with a Bernoulli model? Check each of the conditions specifically.

3. The 2000 Census showed that 26% of all firms in the United States are owned by women. You are phoning local businesses, assuming that the national percentage is true in your area. You wonder how many calls you will have to make before you find one owned by a woman. What probability model should you use? (Specify the parameters as well.)
