In a video game factory, machines A, B and C manufacture 20%, 30% and 50% of the total output, respectively. Also 5%, 3% and 7% of their outputs are defective, respectively. A video game is selected at random . 3 machines are A, B, and C. A produces 20% of the output. B produces 30% of the output.
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.
Given Information :
In a video game factory, machines A, B and C manufacture 20%, 30% and 50% of the total output, respectively. Also 5%, 3% and 7% of their outputs are defective, respectively.
A video game is selected at random .
3 machines are A, B, and C.
A produces 20% of the output.
B produces 30% of the output.
C produces 50%of the output.
output of machine x is 5% defective.
output of machine y is 3% defective
output of machine z is 7% defective.
1. find the probability that an item (video game) is defective.
2. find the probability that the defective part is from machine A, machine B, machine C.
defective parts from machine A are 0.2 * 0.05 = 0.001 of the total.
defective parts from machine B are 0.3 * 0.03 = 0.0009 of the total.
defective parts from machine C ar...
