The researchers found that pedestrians walk against traffic on the UMD College Park campus at the rate of 2 persons every 30 minutes. What is the expected number of pedestrians walking against traffic in an hour? What is the probability of two pedestrians walking against traffic in 30 minutes? What is the probability that no pedestrian walking against traffic in an one-hour 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.
