Explanation Approach: If A = [ a i j ] and B = [ b i j ] are matrices of the dimension m × n , then their sum is A + B = [ a i j + b i j ] of the dimension m × n . The sum of two matrices of different dimensions is undefined. Calculation: For calculating the sum, take the addition of the corresponding elements as follows, [ 4 − 1 2 − 3 ] + [ 2 − 1 To determine (b) To find: The sum [ 2 − 1 3 4 0 − 2 ] + [ − 2 1 − 3 − 4 0 2 ] , if possible. To determine (c) To find: The sum [ 3 9 6 0 4 − 2 1 − 1 0 ] + [ 3 9 6 0 2 − 4 ] , if possible. To determine (d) To find: The sum [ 1 − 1 1 ] + [ − 1 1 1 ] , if possible.

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 re…

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.
