8. Suppose the earth is a sphere with equation r2 + y? + 22 1. On this earth, Edmonton has coordinates (sin(7/6) cos(0), sin(/6) sin(0), cos(7/6)) and Hamburg has coordinates (sin(7/6) cos(/3), sin(7/6) sin(7/3), cos(7/6)). Is it possible to see Edmonton and Hamburg at the same time? How far off the earth must you be?

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.
