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.

Q(1)
Since, given relation R is
R={(1,2),(2,3),(3,4)}
Since,we can see that
(1,2) belong to in Relation R. that is
Or we can write as
1R2 (means 1 is related to 2).
But (2,1) is not belong to in relation R.that is
R
Means 2 is not related to 1.
So only (a) and (b) options are true.
Ans is
(a)
(b) 1R2
