The number of traffic accidents at a certain intersection is thought to be well modeled by a Poisson process with a mean of 3 accidents per year. a) Find the mean waiting time between accidents. b) Find the standard deviation of the waiting times between accidents. c) Find the probability that more than one year elapses between accidents. d) Find the probability that less than one month elapses between accidents. e) If no accidents have occurred within the last six months, what is the probability that an accident will occur within the next year?
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.
