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.

Find the probability that on a given day, majority of the stocks will increase in value.
Solution:
Majority of the stocks means at least of the stocks will increase in value. Hence, we need to find P[x23].
P[x > 3] = P[x = 3] + P[x = 4] + P[x = 5]
= f (3) + f(4) + f(5) = 0.10 + 0.05 + 0.01 = 0.16
Therefore, the probability that majority of the stocks will increase in value is 0.16.
