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 2)
See .png
Given
Comparing it with slope-intercept form
So one point in graph is (0,2) and when y=0, x will be
So the two points to draw graph are (0,2) and (2,0)
For g(x)=x
When x=1,y=1 and x=2,y=2
Using the points (1,1) and (2,2) graph can be drawn
To find the property used is
So here it will be
The graph this will be parallel to X-axis where y=2
