Airline passengers arrive randomly and independently at the passenger screening facility at a major international airport. The mean arrival rate is 10 passengers per minute. a. What is the probability of no arrivals in a 1-minute period? If required, round your answer to six decimal places. b. What is the probability of 3 or fewer arrivals in a 1-minute period? If required, round your answer to three decimal places. c. What is the probability of no arrivals in a 15-second period? If required, round your answer to three decimal places. d. What is the probability of at least 1 arrival in a 15-second period? If required, round your answer to three decimal places.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
