When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 5%. Let X be the number of defective boards in a batch of 250 boards. The condition of any particular board is independent of that of any other board. What is the approximate probability that there are exactly 10 defectives inthe batch?
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.
