Question 1. The following system of linear equations has 2 parameters a, b e R: X1 = 1 X1 +x2 X1 +x2 +X3 = 3 = 6 +x2 +x3 + ax4 = b+6 1) Write the augmented matrix of the system and use elementary row operations to change it to a simpler form. 2) For what values of the parameters a, b does the system have a unique solution? Find that solution. 3) For what values of the parameters a, b does the system have no solution? 4) For what values of the parameters a, b does the system have infinitely many solutions? Find those solutions.

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.
