A bag of 30 tulip bulbs purchased from a nursery contains 12 red tulip bulbs, 10 yellow tulip bulbs, and 8 purple tulip bulbs. 2A) Draw a tree diagram to determine the possible outcomes for pulling two bulbs out of the bag. As in; a column for the first bulb pulled, arrows connecting to the second column for the second bulb pulled, and a third column to list the outcome of the two pulls. 2C) What is the probability that two randomly selected tulip bulbs are both red? 2D) What is the probability that the first bulb selected is yellow and the second is red?
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.
