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.

Question
![The image presents a matrix multiplication problem.
3. \[
\begin{bmatrix}
6 & 5 \\
-4 & -3 \\
7 & 6
\end{bmatrix}
\begin{bmatrix}
2 \\
-3
\end{bmatrix}
\]
Explanation:
- The problem involves multiplying a 3x2 matrix with a 2x1 matrix.
- Matrix multiplication is conducted by taking the dot product of rows from the first matrix with the columns of the second matrix.
- The result of this multiplication will be a 3x1 matrix.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbb1a8ba3-371b-48d7-95b6-c118f740fa83%2Fb2b9989e-1b2f-4fe9-94c3-89c4831d975b%2Fqk2rub_processed.png&w=3840&q=75)

![**Topic: Matrix-Vector Multiplication Exercises**
**Exercise Instructions:**
Compute the products in Exercises 1–4 using:
1. **The Definition:** Follow the method shown in Example 1.
2. **The Row–Vector Rule:** Use the row–vector rule for computing \(Ax\).
If a product is undefined, explain why.
---
### Example 1
#### Definition Method:
The definition method for matrix-vector multiplication involves taking each element of the resulting vector as the dot product of a row vector from the matrix \(A\) and the column vector \(x\).
#### Row-Vector Rule:
The row–vector rule states that the product \(Ax\) can be computed by multiplying each row vector of the matrix \(A\) by the column vector \(x\), and the results form the elements of the solution vector.
---
*Note: When performing matrix-vector multiplication, ensure that the number of columns in the matrix \(A\) matches the number of rows in the vector \(x\). If this condition is not met, the product is undefined.*
---
**Proceed with Exercises 1–4 using the above methods for each computation.**](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbb1a8ba3-371b-48d7-95b6-c118f740fa83%2Fb2b9989e-1b2f-4fe9-94c3-89c4831d975b%2Fqsnyd75_processed.png&w=3840&q=75)
