Find a method that uses the Dot-Product to decide for three randomly chosen points P, Q, and R in 2-space, if they all lie on a straight line, or not. Describe how you'd do it, and explain why it works. Hint: Use the vectors PQ and QR. Picture!!! What adjustments need to be made if you are in 3-space, or in higher dimensions?

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.
