On any given work day, Lillian notices that as she's driving to school, she is first stopped by a red light 80% of the time. Second, she also notices that she is stopped by a train 60% of the time. What is the probability that she was stopped by both a red light and train given she was stopped by a red light? What does your answer say about these two events? (Hint: If you are not sure look at the probability of getting stopped by both!)

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.
