Can you help with those exercises 1-There is a product that is defective with a probability of 0.03. They are sold in packages of 12. The company offers money back if two or more are defective. What is the probability that a given package will be returned for cash? 2-From Experience, you know that the probability that you will make a sale on any given telephone call is 0.23. Find the probability that your first sale on any given day will occur on your fourth or fifth sales call. Calculate the mean and standard deviation of the geometricdistribution. 3-The mean number of accidents per month at a certain intersection is 3. Find the probability that in any given month at least two accidents will occur at this intersection? Calculate the mean and standard deviation of the Poisson distribution. 4-Two cards are selected, without replacement the first card, from a standard deck. Find the probability of selecting a king and a queen. 5-A coin is tossed and a die is rolled. Find the probability of getting a head and then rolling a 6.
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.
