An airport in a country that has an elevated occurance of terrorism profiles airline passengers and semi-randomly selects who will undergo additional screening. If one person is stoped, everyone they are traveling with is also stopped. Over the course of several months, the airport security stops 15% of passengers for this extra screening. On a certain day, 519 passengers go through security at this airport. Let the variable be the number of those people who are chosen for additional screening. Is the number of passengers who are chosen for additional screening a binomial random variable? Select all that apply.

No. There is not a fixed number of trials.

No. The trials cannot reasonably be assumed to be independent.

No. The outcomes cannot be described as only "success" and "failure."
