In a hamster breeder’s experience, the number X of live pups in a litter of a female not over twelve months in age who has not born a litter in the past six weeks has the probability distribution: ? 3 4 5 6 7 8 9 ?(?) 0.04 0.10 0.20 0.31 0.22 0.05 0.02 a. Find the probability that the next litter will produce five to seven live pups. b. Find the probability that the next litter will produce at least six live pups. c. Compute the mean and standard deviation of X.
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.

a. Find the probability that the next litter will produce five to seven live pups.
b. Find the probability that the next litter will produce at least six live pups.
c. Compute the mean and standard deviation of X.
