Suppose a certain towing service receive requests for assistant in an average of 10 per hour. Let the random variable X denotes the number of requests receiving per hour. Find the probability of exactly three requests in 30 minutes.
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.
Suppose a certain towing service receive requests for assistant in an average of 10 per hour. Let the random variable X denotes the number of requests receiving per hour.
Find the
Given, the number of requests for assistance received by a towing service is a Poisson process with rate = 10 per hour
Let X be the number of requests received during 30 minutes period => t = 1/2 hour
=> = *t
= 10*1/2
= 5
