Frames are produced in 3 different machines in a factory. 30% of frames are produced in C1 machine and 50% of frames in C2 machine. Due to workmanship defects, C1, C2 machine 5% and C3 machine 5% defective products. What is the probability that a randomly selected frame is produced on the C2 machine if it is defective? A) 18.96% B) 28,66% C) 28,46%
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.
