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 1313 %, can you model your chance of having your baggage opened with a Bernoulli model? Check each of the conditions specifically. Trials are Bernoulli if the following three conditions are met. 1. There are only two possible outcomes (called success and failure) for each trial. 2. The probability of success, denoted p, is the same on every trial. 3. The trials are independent. Let the act of inspecting a baggage be a trial. Are there only two possible outcomes?

Yes, you can model using Bernoulli model and Yes there are only 2 possible outcomes.

Step-by-step explanation:

Checking Conditions:

1. There are only 2 possible outcomes

You either open a bag for inspection OR you don't

2. The probability of success (opening a bag) is 12% regardless of how many trials there are. THe probability doesn't change later or sooner.

3. The trials are independent of each other. It doesn't matter whether the previous person's bag was opened or not. Doesn't depend on previous event that happened. So trials are independent.

Thus, we can use a Bernoulli Model here.
