Compute the probability of no arrivals in a one-minute period. Compute the probability that three or fewer passengers arrive in a one-minute period. Compute the probability of no arrivals in a 15-second period.
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.
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.
- Compute the
probability of no arrivals in a one-minute period. - Compute the probability that three or fewer passengers arrive in a one-minute period.
- Compute the probability of no arrivals in a 15-second period.
- Compute the probability of at least one arrival in a 15-second period.
