Prove that ifV is a finite-dimensional vector space over a field F, then a subset (B, B2,.. Bn) of V is a basis for V over F if and only if every vector in V can be expressed uniquely as a linear combination of the B.
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.
First, show that if each vector in can be uniquely expressed as a linear combination of the ,then is a basis for .
Suppose that each vector in can be uniquely expressed as a linear combination of the .
Then the set of vectors generates V .
Since , this expression is the unique linear combination of the that yields the zero vector.
Hence, the vector , are linearly independent.
