Suppose that the number of car accidents per day in Wilmington, NC has been recorded for the past year. The table below is a probability distribution table representing the data collected. Number of accidnets 0 1 2 3 4 Probability .12 .32 .25 .13 b) b) Find the probability that there will be at least 2 accidents
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.
