It is speculated that an impurity exists in 30% of all water refilling stations in Metro Manila. To be able to solve the problem, you were tasked to test randomly 10 refilling stations. Using the binomial distribution what is the probability that more than 3 refilling stations have the impurity assuming that the speculation is correct?
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.
