Let the number of cars passing through an intersection be modeled by a Poisson random variable. During 1 day, on average, 200 cars pass through the intersection. a) For a given 1 day time period, what is the probability that at least 225 cars pass through the intersection? (Accuracy to 2 decimal places is required. Answer as a decimal and not percentage.) b) Now consider a given 7 day time period. What is the probability that less than or equal to 1370 cars pass
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.
Let the number of cars passing through an intersection be modeled by a Poisson random variable. During 1 day, on average, 200 cars pass through the intersection.
a) For a given 1 day time period, what is the probability that at least 225 cars pass through the intersection?
(Accuracy to 2 decimal places is required. Answer as a decimal and not percentage.)
b) Now consider a given 7 day time period. What is the probability that less than or equal to 1370 cars pass through the intersection?
Accuracy to 3 decimal places is required. Answer as a decimal and not percentage.
