Two numbers are successively selected at random and with replacement from the set {1,2,···,5}. (i) Find the sample space s={(1,1),(1,2),···}. (ii) LetAbe the event that the first number is equal to the second. Find A and P(A). (iii) Let B be the event that the first number is greater than the second. Find B and P(B).
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.
