According to flightstats.com, American Airlines flights from Dallas to Chicago are on time 80% of the time. Suppose 20 flights are randomly selected, and the number of on-time flights is recorded.
(a) Explain why this is a binomial experiment.
(b) Determine the values of n and p.
(c) Find and interpret the probability that exactly 12 flights are on time.
(d) Find and interpret the probability that fewer than 12 flights are on time.
(e) Find and interpret the probability that at least 12 flights are on time.
(f) Find and interpret the probability that between 10 and 12 flights, inclusive, are on time.
(a) Identify the statements that explain why this is a binomial experiment. Select all that apply.
A. The experiment is performed a fixed number of times.
B. The probability of success is different for each trial of the experiment.
C. The trials are independent.
D. The experiment is performed until a desired number of successes are reached.
