United Airlines' flights from Chicago to Seattle are on time 80% of the time. Suppose 11 flights are randomly selected, and the number on-time flights is recorded. Find the following probilities. (Round your answer to 4 decimal places.) The probability that at least 8 flights are on time. The probability that at most 8 flights are on time. The probability that exactly 4 flights are on time.
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.
