At a chocolate company, on average 5 chocolate are poisonous which makes children sick. a. What is the probability that exactly 8 children will become sick after taking the chocolate? b. What is the probability that at least 3 children will be sick?
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.
At a chocolate company, on average 5 chocolate are poisonous which makes children sick.
Given: Average 5 chocolate are poisonous which makes children sick means λ = 5.
The pmf of poisson distribution is:
a.
The probability that exactly 8 children will become sick after taking the chocolate is 0.06528.
