Suppose that the random change in value of a financial asset is X over the first day and Y over the second. Suppose also that Var(X) =18, and Var(Y) =26 In this case, the total change in the value over these two days is given by X +Y. Do you have enough information to compute Var(X + Y)? If so, compute this value. If not, explain what additional information you need to do so.

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.
