In circuit board testing, the chance that a particular diode will break is 0.01. Suppose a circuit board contains 200 diodes. a. How many diodes do you expect to break? b. What is the chance that at least 4 diodes will be damaged in a randomly selected circuit board? c. If 5 circuit boards are shipped to a particular customer, what is the chance that at least 4 will work?
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.
