Consider the probability distribution of a random variable x. Is the expected value of the distribution necessarily one of the possible values of x? No. The expected value can be a value different from the exact value of x.Yes. The expected value must always be one of its possible values of x. No. The expected value will never be one of its possible values of x.Yes. The expected value can never be a value from the exact value of x. Explain or give an example.
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.
