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.
In a sample of 18 cats from a population with a
First determine the values for the formula, if more than one success is possible, list each separated by a comma:
X =
n =
p =
The Excel formula for binomial distribution is =BINOMDIST(X,n,p,FALSE). But because you're looking for the probability of AT MOST TWO cats whose coat is monocolor, what mathematical calculation will you need to perform on the individual probabilities? (add, subtract, multiply, divide, etc.)
Use Excel to calculate the probability of choosing AT MOST TWO cats whose coat is monocolor. (copy & paste your answer from EXCEL to at least 4 significant figures - make sure your probability copies over and not your formula).
