Draw a tree-diagram to represent all probabilities for the following. A bag contains 14 blue and 8 purple marbles. Two marbles are selected at random without replacement from the bag. What is the probability that the marbles are NOT the same color? I'm confused about the initial set up for tree-diagrams so I'm not sure how to do this correctly. I know there are 22 marbles on the first attempt the probabilty for selecting each color is 14/22 and 8/22 how ever I'm confused on how to proceed.
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.
