Consider the application of the simplex method to an LP of standard form. Assume that the rows of the matrix A are linearly independent. Give either a proof or a counterexample to the following statements. a. An iteration of the simplex method may move the feasible solution by a positive distance while leaving the cost unchanged b. A variable that has just left the basis can not reenter in the very next iteration c. A variable that has just entered the basis can not leave in the very next iteration

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.
