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.

2. Let S be a nonempty bounded subset of R and let m = sup S.
Prove that m is in S iff m = maxS
3. Let S be a nonempty bounded subset of R. Prove that maxS and
supS are unique.
4. Let S be a nonempty bounded subset of R. Let k be a real
number. Define kS = {ks: for some s in S}
Prove the following:
[a] If k >0, then sup(kS) = k(supS) and inf(kS)=k(infS)
[b] if k < 0, then sup(kS) = k(infS) and inf(kS) = k(supS)
5. Let S and T be nonempty bounded subsets of R with S a subset of
T. Prove that infT < infS <supS < supT
