a. ) 'B' option is the correct answer as it gives the correct definition of binomial experiment.
b.) On an average for a large poll conducted percent of people looking the service of airlines = 64%
Probability of selecting a person who likes airline service = .64
Probability of selecting a person not liking airline service= .36
Therefore from a group of 15 people probability of having exactly 8 people liking the service, for this we need to select 8 people from group which like service , so ways to select =15C8
Therefore probability = (15C8)*(.64^8)(.36^7) = 0.1419
