The time between arrivals of vehicles at particular intersection follows an exponential probability distribution with a mean of 10 seconds. a. What is the probability that the arrival time between vehicles is 8 seconds or less? (Note: without calculation process, no credit) b. What is the probability of 20 or more seconds between vehicle arrivals?
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.
