All changes saved O 2. Given the discrete random variable X: What is the probability distribution of X if X ~ B(2, 5)? O P(X = 0) = 0.415 P(X = 1) = 0.087 P(X = 2) = 0.498 О Р(X— 0) — 0.498 P(X = 1) = 0.415 P(X = 2) = 0.087 О Р(Х— 0) -- 0.087 P(X = 1) = 0.415 P(X = 2) = 0.498 O P(X = 0) = 0.415 P(X = 1) = 0.498 P(X = 2) = 0.087
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.

Question 1:
A math test has 10 multiple-choice questions, each with 3 answers to choose from. If a person taking this test were to guess on every question, what is the probability that they will receive a grade of 70 or above?
Question 2: iven the discrete random variable X: What is the probability distribution of X if X∼B(2, 517)?
