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?

The Needleman-Wunsch method for aligning DNA sequences assigns 1 point whenever a mismatch occurs, and 3 points whenever a gap (insertion or deletion) appears in a sequence. Assume that under certain conditions, the number of mismatches has mean 7 and standard deviation 4, and the number of gaps has mean 2 and standard deviation 1. Find the mean and of the Needlemen-Wunch score.
