1.Suppose a fair coin and a fair die is tossed and A is an event that an even number and a tails appear, what is the number of outcomes in A? 2.Let X be a random variable that denotes the number of heads which appear in tossing a coin twice. Which of the following cannot be a value of the random variable X?
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.
