People enter a line for theDemon Roller Coaster at the rate of 4 per minute. The following formula from probability can be used to determinethe probability that x people will arrive within the next minute. P(x) = 4xe-4/x! wherex! = x . (x - 1) . (x - 2) .g. 3 . 2 . 1(a) Determine the probability that x = 5 people will arrive within the next minute.(b) Determine the probability that x = 8 people will arrive within the next minute.
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.
