The number of customers arriving at the outtakes food stand during lunch hour is poison distributed with at the rate of 2.2 customers or minute. What is the probability that one or more customers will arrive in one minute during lunch hour?
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.
The number of customers arriving at the outtakes food stand during lunch hour is poison distributed with at the rate of 2.2 customers or minute. What is the
Solution:
Let X be the number of customers will arrive in one minute during lunch hour.
From the given information, X follows Poisson distribution with parameter λ=2.2.
