. You have a bag with marbles in it: 3 red and 2 blue. Use a tree diagram to show all of the outcomes of drawing a marble out of the bag two different times (with replacement). Note: there are only two options each time: red or blue. However, the probabilities are not equal – this is NOT a fair bag of marbles. There should be four pathways in your tree diagram. However, the weights on the branches are not all the same. Using your tree diagram from above, construct a table showing the probability distribution for the events: 2 reds, 1 red, and 0 red. Using your tree diagram and probability distribution from above, what is the probability that the person pulled out two blues, or P (B, 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.
