There is an average of four accidents per month at an intersection. Assume that a month has 30 days. what is the probability of no accidents during the next 7 days?
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.

My workings are pr(X=0) which is (e^-0.9333 x 0.9333^1) ÷ 0! = 0.3932.
The answer I got on bartleby was to do Complement theorem and take 1 - 0.3932. Why do I need to minus?
