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.

Note: According to Bartleby guidelines; for more than three questions asked, only the first three are to be answered.
Solution for a:
Given
This set is equal to,
Note that the set is the straight line of length 1.
Hence the set will be the strip [0,1] on the axis.
