A- In a certain factory, machines I, II, and III are all producing steel rods of the same length. Of their production, machines I, II, and III respectively produce 2%, 1%, and 3% defective steel rods. From the total production of steel rods in the factory, machine I produces 35%, machine II produces 25%, and machine III produces 40%. If one steel rod is randomly selected from the total steel rods produced in a day, find the probability of defective steel rods? What is the probability that the selected defective rod is made by machine I?

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.
