a. Prove that the intersection of two equivalence relations on a nonempty set is an equivalence relation. p. Consider the equivalence relations R2 and R3 defined on Z by a R2 b if a = b (mod 2) and a R3 if a = b(mod 3). By (a), R1 = R2 N R3 is an equivalence relation on Z. Determine the distinct equivalence classes in R.

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 re…

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.
