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.

![## Sample Math Problem
### Problem
Solve the following mathematical expression:
\[ -6.3 - (-2.7) = \]
### Solution
To solve the expression \(-6.3 - (-2.7)\):
1. Recognize that subtracting a negative number is the same as adding the absolute value of that number. Therefore, \(-6.3 - (-2.7)\) is equivalent to \(-6.3 + 2.7\).
2. Perform the addition:
\[ -6.3 + 2.7 \]
3. To add a negative and a positive number, subtract the smaller number from the larger number, while keeping the sign of the larger number. Here, the larger absolute value is 6.3 with a negative sign:
\[ 6.3 - 2.7 = 3.6 \]
Keeping the sign:
\[ -3.6 \]
Thus,
\[ -6.3 - (-2.7) = -3.6 \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb614cecd-2dbc-4e7c-af5f-0f6b495ec878%2Faf6f2af2-fb5f-469b-bc9d-840222488fef%2Ftvvonv_processed.jpeg&w=3840&q=75)
