There are 12 different books in a bag. In how many ways can we take 4 books from the bag and stack them onto a shelf? (d) You own 6 distinct pairs of shoes but keep all the individual shoes mixed up in the closet. Suppose you close your eyes and randomly select 4 shoes from the closet. What is the probability that you will get no matching pairs?
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.
