A medical study recently documented that 905 mistakes were made among the 289,411 prescriptions written in one year at a large metropolitan teaching hospital. Suppose a patient is admitted with a condition serious enough to warrant ten different prescriptions. Approximate the probability that at least one will contain an error.
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.

I know we are to use Poisson's limit approximation to the binomial in this problem, but is the n=289,411 or is it n=10? I guess because of the large n=289,411 and small p=905/289,411 is what makes it a Poisson limit problem, but then how can we just switch to saying n=10?
