5. Amy the ant is walking along a path r(t) formed by the intersection of two rock surfaces. One surface, a curved vertical wall, is described by y = x² and the other surface is a plane described by z = x + y. (Ground level would be the ry-plane). Amy is walking on r(t) in such a way that her x-coordinate is given by x(t) = t. At some time, t*, Amy is at the point P(1,1,2).

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.
