Empirical probability is a probability that you calculate from actual events that have occured. Flip a coin 15 times and record the results. (Yes, an actual, real coin! Or use your phone…) a What is your empirical probability that you flip a head? b. Do you think the coin that you used is fair? Why or why not? c. Suppose you toss a fair coin 1000 times. Should you expect to come up with heads exactly 500 times? Why or why not?
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.
