A particularly long traffic light on your morning commute is green 20% of the time that you approach it. Assume that each morning represents an independent trial. a. Over five mornings, what is the probability that the light is green on exactly one day? b. Over 25 mornings, what is the probability that the light is green on exactly five days? c. Over 25 mornings, what is the probability that the light is green on more than five days?
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.
