Suppose you have a loaded coin that when flipped is likely to land on heads about 20% of the time and on tails 80% of the time. If you flip this coin three times what is the expected value for tails? What is the variance and standard deviation? What is the probability of you getting two tails?
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.
