The TSA Is using an experimental computer to randomly select airline passengers

Question

The TSA Is using an experimental computer to randomly select airline passengers for additional screening. Each person has a 0.7% chance of being selected. They test the new computer until 10 passengers are chosen for the additional screening, and then they remove it. Let the random variable be the number of passengers who pass through security until 10 are stopped for additional screening. Is the number of passengers who pass through security in this time a binomial random variable? Select all that apply D Yes. All four conditions are met. a No. There is not a fixed number of trials D No. The trials cannot reasonably be assumed to be independent. No. The outcomes cannot be described as only "success" and-failure." No. The probability of success is not the same for each trial

Explanation / Answer

Solution:

No, the number of passengers who pass through security until 10 are stopped is not a binomial random variable. This is because there are no fixed number of trials here.

So the option B i.e. No. There is not a fixed number of trials , should be selected.

Moreover here the random variable follows Negative Binomial distribution.
