1) An easy way to increase password security is to require that each password have at least a certain minimum length. This certainly helps increase the number of possibilities. a) Assuming that the password is NOT case-sensitive and that letters can be used more than once, how many 6 letter passwords are possible? b) Investigate how this changes as the minimum length is increased by finding the number of possible 8 and 10 letter passwords under the same assumptions.

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.
