Xenia has a bag which contains 5 red marbles and 4 pink marbles. She draws marbles one at a time without replacement until she draws a pink at which point she stops. Let R be the random variable which counts the number of red marbles that have been drawn when she stops. Compute Pr[R≥1].
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.
