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.

400 feet apart and rise 90 feet above the horizontal. A cable strung between the tops of the towers has the shape
of a parabola, with center point 10 feet above the roadway. Find the equation of the parabola. Set-up the
integral that will give you the length of the cable and then use your calculator to evaluate the integral.
