Every week an animal shelter gives two animals randomly to two loving families for free. This week there are 9cats and 5 dogs in the shelter. The animal's names are written on cards, and two cards are drawn, one at a time, without replacement. The first family in line gets the animal whose name is on the first card, and the second family gets the animal whose name is on the second card. (a)Draw a tree diagram. (b)Find the probability that the first family in line gets a cat and the second family gets a dog.
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.
