In a computer game, a certain building called the archer tower must be upgraded to improve its functions. If upgrading it to level 1 takes one day, upgrading it from level 1 to level 2 takes two days, upgrading it to level 3 takes three days, and so on, how long will it take for the archer tower to reach its optimal function if its maximum level is 15?
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.
