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.

![### Algebraic Fraction Simplification
Simplify the following expression:
\[
\frac{2a - 1}{2a - 3} - \frac{2a^2 - 5a + 4}{8a^2 - 22a + 15} - \frac{3a - 2}{4a - 5}
\]
Choose the correct simplified form from the options provided:
- \(\circ\) \(-\frac{3}{7}\)
- \(\circ\) \(\frac{1}{2a - 3}\)
- \(\circ\) \(\frac{2a^2 - 6a + 15}{8a^2 - 22a + 15}\)
#### Explanation of the Problem
In this algebraic expression, we are given three rational expressions involving the variable \( a \). To solve the problem, we need to find a common denominator among the fractions, combine them, and then simplify the resulting expression.
Each option represents a possible simplified form of the given expression. Attention must be paid to the arithmetic involving polynomials in both the numerators and the denominators.
#### Detailed Steps
1. Identify the least common multiple (LCM) of the denominators.
2. Rewrite each fraction with the LCM as the new denominator.
3. Combine the numerators according to the arithmetic operations.
4. Simplify the resulting expression, if possible.
This type of problem helps in understanding the methods used for handling complex rational expressions and is foundational for higher-level algebra and calculus.
