Cards. Cards numbered 1,2,3, . . . ,10 are placed in a box. The box is shaken, and a blindfolded person selects two successive cards without replacement. a. What is the probability that the first card selected is numbered 6?b. Given that the first card is numbered 6, what is the probability that the second is numbered 9?c. Find the probability of selecting first a 6 and then a 9.d. What is the probability that both cards selected are numbered over 5?
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 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.
