A poll reported that 61% of adults were satisfied with the job the major airlines were doing. Suppose 20 adults are selected at random and the number who are satisfied is recorded. Complete parts (a) through (e) below.(a) Explain why this is a binomial experiment. Choose the correct answer below.A. This is a binomial experiment because there are three mutually exclusive outcomes for each trial, there is a fixed number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial.B. This is a binomial experiment because there are two mutually exclusive outcomes for each trial, there is a random number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial..This is a binomial experiment because there are two mutually exclusive outcomes for each trial, there is a fixed number of trials, the outcome of one trial does not affect the outcome of another, and the probability of success is the same for each trial.D. This is a binomial experiment because there are two mutually exclusive outcomes for each trial, there is a does not affect the outcome of another, and the probability of success changes in each trial.(b) Find and interpret the probability that exactly 10 of them are satisfied with the airlines.The probability that exactly 10 adults are satisfied with the airlines is(Round to four decimal places as needed.)
